How many days during menstruation does the back hurt? What to do if your lower back hurts during menstruation

More than half of women experience lower back pain during menstruation. Some of the fair sex, if they have lower back pain during menstruation, wonder how to get rid of this phenomenon, but do not bother to find an answer to the question of why pain occurs. Manifestations of discomfort and pain during menstruation can have various causes, including indications of serious diseases.

In addition, the most common pain in women during menstruation is caused by the following factors:

• muscle strain in the pelvic area and contraction of the uterus;
• inflammatory processes or pathologies of internal organs (most often the genitourinary system);
• hormonal disruptions.

Note! To get rid of discomfort and suffering, a woman needs to see a doctor to find out the cause of pain.

It is worth noting that back pain can also occur for other reasons. Whatever it was, do not put off a visit to the doctor.

During menstruation, the main female genital organ contracts. This is necessary to cleanse the uterus, since during contraction, unnecessary substances come out of it. In some girls and women, the contractile movements of the reproductive organ cause pain due to the high sensitivity of the receptors or the active work of the nervous system. In the case when the uterus is displaced back to the spine, the woman feels pain during contraction in the lower back or sacrum.

Note! Pain during menstruation in the lower back is called radiating, that is, pain is felt in the wrong place where it occurs.

In women after 35 years of age, there is often an increase in estrogen levels, the concentration of which reaches its maximum value during menstrual bleeding. This female hormone promotes uterine contraction, its increased concentration increases the number of contractile movements, which can be accompanied by pain, especially in women with a high pain threshold.

Disruptions in the hormonal system can also include violations of the production of another female hormone - progesterone. This hormone is responsible for the production of special active substances called prostaglandins. They are necessary for the contraction of the reproductive organ, but their excessive concentration increases the contraction, resulting in pain.

Note! Women over 35 are more likely to experience hormonal problems, but they can also occur in young women who have not given birth, especially when taking oral contraceptives without consulting a doctor.

The premenstrual period is often characterized by a violation of the water balance. The body retains fluid, which leads to weight gain. Since this process proceeds quite rapidly, the back muscles do not have time to rebuild and the spine experiences a large load, especially in the lumbar region.

With the onset of menstruation, such a phenomenon is accompanied by pain, since the sensitivity of the receptors and painful contractions of the uterus make themselves felt. Violation of the water balance also contributes to the swelling of the organs of the genitourinary system. As a result, there is pressure on the nerve endings in the lumbar region.

If you are worried about why the lower back hurts with the onset of menstruation, you should know that various pathological processes can cause pain:

• pleurisy;
• urolithiasis disease;
• endometriosis (inflammation of the uterus);
• ectopic pregnancy;
• disorders in the support system (osteochondrosis, osteoporosis);
• neurological diseases;
• infectious diseases of the genitourinary system;
• inflammation of the kidneys or adrenal glands, and so on.

Sometimes the symptoms of the disease do not appear between periods. With a change in the hormonal background, which is always observed during menstruation, pain becomes pronounced.

Note! If each time menstruation is accompanied by severe pain in the lower back, it is necessary to undergo an examination and find out the cause. Do not self-medicate, as this can only aggravate the course of the disease.

Sometimes lower back pain during menstruation is accompanied by other unpleasant symptoms:

• nausea;
• weakness;
• vomiting;
• headache.

In this case, it is necessary to visit an endocrinologist and check the functioning of the thyroid gland. Violations in the functioning of this organ affect changes in the hormonal background, and can lead to serious health problems.

If back pain in the lumbar region is accompanied by an increase in temperature to 37.5 degrees or higher, you should urgently seek medical help. These symptoms indicate the development of the inflammatory process.

Some women, faced with lower back pain during menstruation, do not know what to do and which doctor to contact. If you have back pain during your period, after it ends, go to see a gynecologist. He will conduct an examination, and, if necessary, send for an ultrasound. You will also need to take tests.
If the doctor fails to determine the cause of the pain, you need to go to an endocrinologist or other specialists. Special tests will help determine the amount of hormones, and whether it is normal.

Sometimes you may need to consult a therapist, surgeon or neurologist.

Note! With regular pain, a visit to the hospital should not be postponed, since the cause may lie in a serious pathology (up to the formation of a tumor).

Pain is a symptom of a certain disease, so it cannot be treated. To get started, you first need to establish the cause. Treatment depends entirely on the factors that caused the pain. For example, in the inflammatory process, anti-inflammatory drugs are prescribed, and in case of hormonal failures, drugs (sometimes of plant origin) are prescribed to restore the functioning of the hormonal glands, and so on.

When the pain is unbearable, painkillers will help relieve it, which are sold freely in any pharmacy. If you do not know what painkiller to drink, then opt for non-steroidal (non-hormonal) drugs. These include but-shpa, tempalgin, ketanov. But the regular occurrence of pain should not be constantly suppressed by painkillers, since they do not eliminate the cause, but only temporarily relieve the manifestation of the pathology.

It is impossible to use traditional medicine and medicines without a doctor's prescription, as you can harm your health more. Especially in cases where the exact cause of the pain has not been established.

Be attentive to your body. If the lower back hurts once and not very much, maybe you should not be alarmed. But it is also not necessary to endure painful sensations with each menstruation. Remember that pain is a signal of a malfunction in the functioning of individual systems or organs.

Natural processes take place in the female body every month. Menstruation helps to prepare again for a possible pregnancy. It would seem that everything that happens during menstruation should also be a natural process. But then why does the back hurt during menstruation? Is this a kind of normal reaction of the body to what is happening on critical days? Let's look at all these painful processes, what causes them and how to deal with them.

The female body becomes very sensitive at the beginning of the menstrual cycle. This is due to various biological processes, into which there is not much point. The main thing to understand is that pain receptors become more sensitive. It turns out that previously unnoticed pain during menstruation begins to cause real discomfort.

If the uterus is tilted back for various physiological reasons, the woman will be prone to various pains, not only in the abdomen and lower back (found everywhere), but also throughout the back.

Two out of three women regularly experience pain in the back and lower back during menstruation.

If your back hurts during menstruation, this can be either a normal reaction of the female body on critical days or a signal of a serious illness. Most often, the lower back aches, and pains along the entire back are rarer, one might say an atypical situation. How pronounced problems are with the back depends on the duration, frequency and intensity of pain.

What can cause back pain during menstruation

Do not wonder if your back can hurt during menstruation. During this period, anything can hurt. Consider the most popular causes of such pain.

1. Hormonal imbalance is common at the beginning of the cycle. It is fraught with the appearance of various pains.
2. With an increase in the amount of estrogen hormones in the female body, menstruation begins to flow more and more painfully. Therefore, the back may begin to ache, which was not there before.
3. An imbalance between prostaglandins and sex hormones usually leads to pain in the lower abdomen. However, due to the specifics of the body, pain syndromes can go to the back.
4. Back pain during menstruation can occur due to pathology of the uterus.
5. Inflammation of the genitourinary system in some cases can cause aching sensations in the back and lower back.
6. The water balance is disturbed. The fluid does not leave the body as it should, which causes swelling of the tissues.

There are other reasons that can provoke back pain during menstruation. If the pain does not go away, but intensifies, then you should consult a doctor. Also, a doctor's consultation may be required in cases where the back continues to hurt after the end of menstruation.

A striking example is the dysfunction of the thyroid gland, which is impossible to diagnose by yourself. Because of such problems, the back also hurts during menstruation. Associated syndromes usually present, such as nausea with vomiting, poor sleep, and weight loss.

Other causes of pain

Although the back began to hurt around the same time that menstruation began, but this may not be interconnected. It should be understood what causes back pain that is not related to the female cycle:

• excessive muscle load. If the back hurts, then in 85% of cases this is due to the load on the spinal muscles. Problems arise not only when lifting weights, but also because of a sedentary lifestyle;
• intervertebral hernia. It usually occurs in older people. Without a special study, it will not be possible to identify it;
• compression fracture is rare, and most often such a diagnosis is made in older people;
• other rare diseases that cause chronic back pain. During menstruation, the pain just intensifies.

Having figured out why the back hurts during menstruation, it's time to think about treatment.

When you need a doctor

It should be clearly understood that there are situations when you can cope on your own, but if you need a doctor, then you should not self-medicate. Seeking medical attention is mandatory in the following situations.

1. The pain intensifies every day and does not go away with menstruation.
2. The bleeding became more intense.
3. If your back hurts a lot during menstruation, and painkillers help only for a while.
4. Back pain is accompanied by high fever, chills, sweating, aching muscles or joints.
5. In addition to pain, there are symptoms of infection (itching, strange discharge, strange smell, problems with urination, discomfort in the genital tract).

First you need to go to the gynecologist, and he will already determine what additional examinations will need to be done.

What to do with pain

A woman must think about what to do if her back hurts during menstruation. It is extremely important to understand that pain is a manifestation of some kind of problem, so painkillers only eliminate the symptom for a while. You can go one of the following ways:

• take prostaglandin synthesis inhibitors;
• use various hormonal drugs;
• use antispasmodics and analgesics;
• use sedatives;
• engage in non-malignant treatment.

If it was decided not to wait out the back pain, but to do something about it, then you should definitely consult a doctor so as not to harm yourself even more.

Back pain during menstruation worries about 40% of women of reproductive age (from 16 to 45 years). It can be of moderate or high intensity, occur a few days before the onset of menstruation or during it, and also be local, radiating or reflected. The main localization of back pain that occurs during menstruation is the lumbosacral spine (lower back), consisting of five lumbar and five sacral vertebrae. In some cases, the cause of pain is physiological changes that occur in a woman's body during menstruation, but sometimes such pain can indicate various diseases of the genitourinary and reproductive systems, as well as chronic spinal pathologies that worsen during menstruation under the influence of certain hormones.

Menstruation is a cyclic bleeding from the vaginal tract of a woman, which is the initial phase of the menstrual (reproductive) cycle. Pain of varying intensity during menstruation disturbs more than 70% of women, but they are localized mainly in the lower abdomen and are associated with intense contraction of the uterus.

The uterus is a muscular organ that has a pear-shaped shape and is lined from the inside with endometrium - a mucosal (functional) membrane that produces hormones and is abundantly supplied with blood vessels and capillaries.

During menstruation, the endometrium is shed from the body of the uterus and excreted as menstrual fluid, which also contains enzymes, salts, and a secret secreted by the endocrine glands of the vagina and cervix. In order for the endometrial tissue to be able to enter the vaginal tract, the uterus is actively contracting, which provokes a pulling pain in the lower abdomen, which usually occurs 1-2 days before the onset of discharge.

Back pain (mainly in the lower back) can conditionally be considered the norm, since it can also appear under the influence of natural physiological changes in the female body.

In cases where painful sensations cause severe discomfort, are of high intensity, or are accompanied by other alarming symptoms (for example, fever or urination disorder), you should consult a local gynecologist, since some chronic diseases of the musculoskeletal system are exacerbated during menstruation in women with unstable hormonal background.

Common causes of back pain during menstruation are:

• increased synthesis of prostaglandins (sex hormones that regulate the reproductive cycle of women), which increase susceptibility to the main mediators of pain - histamine and bradykinin;
• anatomical features of the structure of the uterus (for example, the location of the uterus closer to the spine or bend towards the spinal column);
• overexertion of the lumbar region caused by sedentary work or physical exertion;
• swelling of the pelvic organs caused by the natural retention of fluid in the body during menstruation.

During menstruation, women are advised to observe emotional peace, since any stress and nervous tension can provoke increased pain both in the lower abdomen and in the back. With chronic stress, women can experience all types of menstrual pain, including headaches.

Increased salt intake as one of the reasons

Salt (sodium chloride) is vital for the normal functioning of the whole organism. Salt components (in particular, chlorine ions) is the main component of hydrochloric acid produced by the parietal cells of the stomach and necessary for the normal digestion of food. Salt also ensures the functioning of the nervous system by participating in the transmission of nerve impulses and improves the nutrition of muscle tissue.

During menstruation, fluid can accumulate in the subcutaneous fat of the pelvic organs, and increased consumption of salty, smoked and pickled foods can increase tissue swelling and cause sharp or aching pain in the lumbar region and coccyx.

Important! The norm of salt for an adult is about 10-15 g, but during the period of menstrual flow, this amount is recommended to be reduced by 2-3 times - up to 5 g per day.

Pathologies of the uterus and their relationship with lumbar pain

Some anatomical features of the structure of the uterus can cause back pain during menstruation. As a rule, such pains are combined with intense pain in the lower abdomen and last until the cessation of menstruation.

Pathologies and anomalies of the uterus that can provoke back pain during menstruation

Note! Any diseases of the uterus (including infectious and inflammatory processes) can cause referred pain in the lumbar region. An alarming symptom is a combination of severe back pain with vaginal discharge that is uncharacteristic of the menstrual period (bad smelling, purulent, interspersed with sediment): such discharge can be one of the signs of cervical cancer, so when they appear, you should immediately consult a doctor.

Back pain due to hormonal imbalance

In the first phase of the menstrual cycle, a woman increases the synthesis of prostaglandins, which are also called inflammatory mediators, as they increase the sensitivity of nociceptive (pain) receptors. Prostaglandins are biologically active substances that are formed by the action of enzymes from certain fatty acids. They are necessary so that the uterus can contract, so an increase in F2α prostaglandins in a woman's body during menstruation is a normal physiological process.

Pain in the lumbosacral segment of the spine may be associated with increased synthesis of prostaglandins in women with uterine pathologies or having an unstable hormonal background. Factors that can affect the level of hormones in the female body include:

• diseases of the endocrine system (diabetes mellitus, hypo- and hyperthyroidism, pancreatitis, etc.);
• malnutrition or errors in eating behavior (frequent use of confectionery, fatty foods, spices);

  

• bad habits and various addictions (smoking, alcoholism, drug addiction);

  

• sedentary lifestyle.

  

Nutrition is one of the main factors in the formation of the mechanism of lumbar pain. Since fatty acids are one of the sources of prostaglandins in the body, during menstruation one should limit your intake of fatty foods(butter, oily fish, high-fat milk and cottage cheese, nuts).

Important! Aspirin (acetylsalicylic acid) inhibits the synthesis of prostaglandins, so one of the methods for reducing lumbar and pelvic pain is drug correction. Women who use aspirin to relieve back pain should be aware that menstrual flow in this case can be plentiful, as the drug thins the blood and increases its fluidity.

Infectious pathologies of the pelvic organs

The pain syndrome that occurs in the lower segment of the spine may be the result of infectious diseases of the pelvic organs related to the excretory and reproductive systems, for example, cystitis or salpingo-oophoritis (referred pain). During menstruation, the most significant factor in the development of infectious and inflammatory pathologies of the pelvic organs is non-compliance with intimate hygiene, so women should especially carefully monitor the cleanliness of the genitals and anorectal space.

Back pain (reflected) in infectious pathologies of the small pelvis

Important! in the lower back in any phase of the menstrual cycle can be a sign of severe surgical pathologies, for example, purulent tubo-ovarian formations or pelvioperitonitis (purulent inflammation of the lower segment of the peritoneum located in the pelvic cavity). These diseases have a rather high risk of mortality, so the timely detection of pathologies in such patients plays a decisive role in the formation of a favorable prognosis.

What diseases of the musculoskeletal system can worsen during menstruation?

During the period of menstruation, the female body becomes especially sensitive and vulnerable, and a change in the hormonal background provokes a temporary exacerbation of sluggish chronic diseases, among which there may be spinal pathologies. The most common diseases of the lumbosacral zone are intervertebral hernias and (disc protrusions that occur when the nucleus pulposus is displaced through the fibrous ring of the intervertebral disc). Back pain can occur not only in the lower back, but also in the cervical and thoracic spine.

Other diseases of the spine that can be aggravated by the action of prostaglandins during menstruation are:

• chronic epiduritis;
• ankylosing spondylitis (Bekhterev's disease);

  

• spondylitis;
• spondylolisthesis;

  

• facet joint syndrome;
• spinal stenosis;

  

• narrowing of the foraminal canal;
• radiculopathy.

  

Note! Some diseases of the musculoskeletal system, such as epiduritis (inflammation of the tissue that fills the epidural space) or spinal epidural abscess, may require the use of surgical methods, so it is not necessary to endure severe back pain while waiting for menstruation to end.

How to relieve pain?

Regardless of the cause of pain, the main way to eliminate it is drugs from the group of non-narcotic analgesics, for example, drugs based on metamizole sodium (Baralgin, Analgin).

Metamizole sodium should be taken no more than 2-3 times a day in a single dose of 500 mg. Despite the effectiveness of "Analgin" in the treatment of acute pain syndromes of various etiology and localization, this drug is less and less used in medical practice due to the high risk of side effects and negative consequences caused by the high toxicity of metamizole sodium.

The drugs of choice for reducing menstrual pain in the back and abdomen are considered by experts to be from the anilide group, for example, Paracetamol.

It is necessary to take paracetamol and its analogues ("Panadol", "Efferalgan") 500-1000 mg up to 3-4 times a day. If paracetamol is ineffective, you can use drugs from the NSAID group: Ibuprofen, Diclofenac, Movalis, Ketorolac.

The duration of taking non-steroidal anti-inflammatory drugs without consulting a doctor should not exceed 5 days.

To reduce muscle tone, stop spasms and reduce the strength of uterine contractions, which can provoke pain in the lower back, the use of antispasmodics is indicated. The most effective and safe for women during menstruation are:

Further therapy is selected taking into account the results of the diagnosis and medical examination. In infectious diseases of the pelvic organs or the spine, antibiotics are prescribed ("Amoxicillin", "Tetracycline", "Hemomycin") and antimicrobial agents with antiprotozoal activity ("Metronidazole").

For fungal infections, for example, fungal cystitis, the use of antimycotics in the form of tablets or injection solutions (Fluconazole, Miconazole) is indicated.

Treatment of severe forms of cystitis, for example, tuberculosis infection of the bladder, is carried out in a hospital and requires the use of special therapy protocols using anti-tuberculosis drugs (Rifampicin, Streptomycin).

If pain and discomfort are provoked by osteochondrosis, displacement of the vertebrae or intervertebral discs, the doctor may recommend wearing an orthopedic bandage - an elastic belt that can be adjusted depending on the size of the woman's pelvis.

The use of semi-rigid corsets for the lower back during menstruation is not recommended.

Treating back pain without medication

In cases where pain in the lumbosacral, coccygeal segment or in another part of the back is the result of natural physiological processes occurring in the body at the beginning of the menstrual cycle, it can be dealt with without the use of drugs.

Wool belt

A dog or goat hair belt is the safest and most effective remedy for back pain. More aggressive heat exposure (eg heat applications, bath, sauna) during menstruation is prohibited, and the belt can be used almost without restrictions. It should be worn throughout the day, and in case of severe pain, it is necessary to leave the product on all night (at least 8 hours).

Note! Some advise to rub the lower back with vodka or alcohol before putting on the belt. Experts do not advise doing this, since ethanol easily penetrates the skin (especially under the influence of heat, when the pores open more), which can cause intoxication in immunocompromised women.

Badger fat ointment

Badger fat is a very effective analgesic and anti-inflammatory agent that is used in folk and traditional medicine to treat coughs. Badger fat also stimulates blood flow to the site of application, which has a positive effect on blood circulation and nutrition of the cartilage tissue that makes up the intervertebral discs. You need to apply the ointment 2-3 times a day (it is better to immediately wrap your lower back with a downy scarf after that).

Advice! For chronic pelvic pain, which increases during menstruation, you can mix badger fat with natural honey (1 teaspoon each), heat the resulting mixture and apply a thick layer on the lumbar region and coccyx. Cover with a warm scarf and leave for 1-2 hours. After the procedure, thoroughly rinse the skin. To improve well-being, it is enough to do 4-5 procedures.

Gymnastics (roller exercise)

Heavy and intense physical activity during menstruation is contraindicated, but if a woman is worried about back pain, it is recommended to perform this exercise daily (see picture below). It will not only relieve pain and discomfort, but also improve blood flow to the pelvic organs, as well as increase the flexibility and elasticity of the spine.

If there is no special gymnastic roller at home, it can be made from a terry towel. Stay in this position for about 1 minute, gradually increasing the time to 2-3 minutes. If you perform this exercise daily, after a month you can forget about pain in the lumbar region.

Video - Causes of lower back pain during menstruation

Back pain during menstruation is a fairly common phenomenon, which is most often a consequence of the physiological characteristics of the body in the first phase of the menstrual cycle. It is possible to fight pain with home methods and pills only after consulting a doctor, since some pathologies that can manifest themselves with such symptoms may require the use of surgical methods of treatment.

Often, women turn to a gynecologist because they have lower back pain, while there is no menstruation, the pregnancy test is also negative.

Pain can be caused, but usually it is mild, and very few women experience severe discomfort during this period.

If the discomfort continues after menstruation, and in general in their absence, it is urgent to consult a doctor to undergo an examination.

Main causes of violations

When the lower back hurts, but there is no menstruation, a number of problems in the body can be suspected.

1. Hormonal shift. It leads to strong contractions of the uterus and pain, as well as to a violation of the excretion of fluid, which provokes swelling of tissues that put pressure on sensitive nerve endings. Soreness is often accompanied by general weakness, migraine, chills.
2. Hyperthyroidism. In addition to pain in the lumbar region, you can notice a deterioration in appetite, sleep, severe emotional instability and premenstrual syndrome.
3. Anatomically abnormal location of the uterus. When the body of the uterus is located too close to the nerve endings, pulling sensations may appear in the lower abdomen and in the lumbosacral region.
4. Hyperstimulation of the ovaries. Usually after the use of hormonal drugs (for example, for the treatment of infertility).
5. Endometriosis. This is a disease caused by the ingress of particles of the inner layer of the uterus (endometrium) outside the uterus and their growth in other areas of the body (from the abdominal organs to the lungs) - under the influence of hormones, these foci continue to bleed, and then collapse.
6. Cysts, tumors of the genital organs. In this case, the lower back hurts, there is no menstruation, which may be due to the growth of neoplasms that compress the nerve endings and disrupt blood flow (which can later lead to tissue necrosis).
7. Inflammation of the appendages. It manifests itself as pain in the lower back and lower abdomen.

These are just some of the factors, and the true cause of the ailment can only be established at a doctor's appointment.

It is important to urgently consult a specialist with an increase in the mammary glands (especially if discharge appears from them), with the appearance of unusual and / or sharp-smelling discharge from the genital organs, diffuse nature of pain and fever.

And, of course, in the case when the menstruation has passed, and the soreness persists.

Relationship between pain and menstruation

Many people know that a woman suffers from pain mainly during periodic bleeding. At other times of the cycle, when there are no periods, she feels normal.

And if after the end of menstruation, the lower back still hurts, this problem is unlikely to be related to the menstruation itself or to ovulation - usually this is a consequence of some kind of pathology.

In this case, it hurts in the abdomen, but sometimes it radiates more strongly to the back, in particular, to the lumbar region.

If, with pain in the back, menstruation does not begin, although the period has already come, it is likely due to either a violation of the functions of the genital organs or pregnancy.

In addition, the first signs of pregnancy are a bit like the approach of menstruation - it can “pull” and “tingle” the lower abdomen and lower back. Usually, the following symptoms also join:

• frequent urination;
• intestinal disorder;
• small spotting;
• headache;
• increased salivation and a change in taste, the appearance of intolerance to odors;
• fatigue, drowsiness;
• growing tenderness of the breast.

It is difficult for a layman to distinguish pain radiating to the lower back from sensations that signal problems with the spine.

It must be understood that the vertebral pathology has no connection with menstruation, the nature of the pain does not change and does not depend on the beginning or end of the cycle.

In the case of gynecological problems, the pain syndrome varies. For example, with endometriosis, cramping or aching pains that radiate to the lower back and rectum persist for quite a long time and intensify a week or two to three days before menstruation.

Menstruation is a consequence of rather complex processes occurring in the female body. Critical days are accompanied by various symptoms, namely bloody discharge, nausea, discomfort in the lower abdomen, etc. Most of the fairer sex is worried about pain in the lumbar region, and more often than those who have not yet given birth. Experts consider this a pathology and recommend contacting a medical institution to find out the cause.

Symptoms

The pain that occurs in the lower back during menstruation is an alarming bell, which indicates a malfunction in the body.

In addition to this symptom, menstruation is accompanied by other symptoms:

• a slight increase in temperature indicators (up to 37.2 ° C);
• intestinal disorder;
• dizziness;
• weakness;
• nervousness;
• soreness in the genital area;
• nausea and vomiting (in rare cases).

It should be understood that many inflammatory processes have similar signs, therefore it is important to be able to distinguish the norm from the pathological condition.

Possible causes of discomfort

Many women believe that pain in the lumbar region during the menstrual cycle is the norm. However, most often it is a pathology. Such a sign can occur 2-3 days before the onset of menstruation, persist throughout the entire period and often after it. The main reason for the appearance of this symptom is considered to be hormonal imbalance.
