When a woman has a sore left breast, it is difficult for her to decide for herself on the true causes of discomfort: pain can be a sign of a wide range of diseases, starting with breast problems and ending with acute diseases of the spleen. How to determine the nature of the problem by the nature of the pain and the aggregate of other symptoms?

Why does the left chest hurt before menstruation?

Every girl knows that her hormonal changes during the month at least twice. The state and development of the mammary gland are completely controlled by sex hormones. Therefore, if at a certain point in a woman's menstrual cycle, her left breast hurts, this often indicates that the content of female hormones in her body has increased and in a short time we can expect menstruation.

Left chest hurts: what to do?Why it happens? Before menstruation, a woman undergoes some changes in her body, which are designed to preserve a possible pregnancy. This increases the mammary glands and when the capsule is stretched, as well as the tension of the skin, the fair sex feels slightly sore.

If it is for this reason that the left chest hurts, what should I do? Nothing to do. Already after the first days of menstruation, the mammary glands will gradually begin to return to their former size and the pain will disappear.


However, there are cases that the left breast increases and for a long time does not return to its previous size, despite the presence or absence of menstruation. In this case, not only hurts the left breast, but also the right.

The cause of mastopathy is the same hormonal advantage in favor of certain hormones. Due to prolonged imbalance, the breast tissue begins to grow and a benign tumor is formed. At the initial stage small nodules form in the mammary glands. The chest itself seems to swell. Because of this, the left breast hurts when pressed, as well as the right breast. It becomes uncomfortable to wear bras, as well as tight clothing.

If you do not treat mastopathy, over time, the pain begins to cause great discomfort. Pain begins to respond in the armpit and even in the shoulder. Under unfavorable circumstances, mastopathy turns into breast cancer, so it is imperative that you seek medical attention at the first symptoms of the disease.

It hurts the left breast, not only because of the presence of any disease. Often, pain in this area is the result of injuries. Bruising, wearing a bra of unsuitable shape and size can all lead to swelling and pain in the area of ​​the left breast.

You should also pay attention to what kind of physical activity a woman receives, because under the mammary glands there is also a layer of muscles. It is muscle pain that can cause discomfort.

In such cases, it is necessary to change the underwear to a more comfortable option, and also to ensure the rest of the pectoral muscles. If the pain does not go away within two to three weeks, then this is the reason to immediately consult a doctor.

Why does the left breast hurt during pregnancy?

Causes of chest pain during pregnancy - increased levels of hCG. This hormone causes changes in the body of the future mother, which will allow to carry the child.

Why does the left chest hurt? She, like the right, is preparing to become a source of nutrition for the child, so they increase in size and already in the first trimester of pregnancy begin to fill with colostrum. Sometimes from the nipples of a pregnant woman involuntarily begins to stand out colostrum. Themselves nipples darken.

The nature of pain in all women is different: sometimes pinching only the nipples, and sometimes it is impossible to touch the entire breast as a whole. All these symptoms go away by 10-12 weeks of pregnancy. If this does not happen, then it is worth consulting with your doctor about this.

The main thing during this period is to wear comfortable underwear and, if necessary, use absorbent pads that will eliminate the traces of colostrum on the bra.

Why does the left breast hurt when a woman has already given birth to a child and feeds him with mother's milk?

For those women who feed the baby for the first time, mastitis often happens - an inflammation of the mammary gland. The cause of mastitis is a bacterial infection, often triggered by Staphylococcus aureus.

Pain in the inflamed mammary gland with mastitis is accompanied by chest reddening, fever, and poor health.

Mastitis in no case can not be ignored, because in advanced cases gangrene develops. It is also not recommended to treat this disease on its own, as it is necessary to precisely determine the type of mastitis in order to avoid complications. Moreover, such a disease is dangerous not only for the mother, but also for the child herself.

Breastfeeding during mastitis is prohibited, and the mother herself should be treated with antibiotics. Milk from the inflamed breast is periodically decanted. If conservative treatment does not help, surgery is possible.

Does the left breast hurt badly? If a woman is far beyond forty, then this may well be a sign of the approaching menopause. In such cases, along with acute pain, heaviness in the chest area, swelling and even burning can be observed.

The cause of all these symptoms is a change in hormonal levels. Acute chest pain appears cyclically right during a hormonal imbalance.

To cope with this pain will only help the doctor, with whom the woman must develop a range of tools to combat menopause. However, checking the mammary glands for benign or malignant neoplasms is a mandatory procedure, especially after forty years.

If the examination showed that the mammary glands of women are normal, then massage can be used to reduce the pain, as well as cold compresses. Nevertheless, the main emphasis should be placed on the regulation of hormonal background with the help of special preparations.

Myocardial infarction

If the left chest hurts, it gives to the scapula, to the arm, to the shoulder, and this pain is not appeased either by anesthetics or nitroglycerin - an urgent need to contact a cardiologist or therapist.

The scourge of our time is myocardial infarction. Moreover, this heart disease is “younger” and is increasingly common in people aged from forty to fifty years. The pain of a heart attack is practically not confused with any other: it is localized as if to the left, but extends to the entire chest, and manifests as a “tightness” or “tightness” in the chest.

In addition to giving back pain to the left arm, its response is sometimes observed in the jaw, in the back or in the stomach. At the same time, waiting for the painful sensations to pass by themselves is a big mistake. Delay in such cases can cost a person life.

Angina pectoris

Sore left chest on top and with other diseases of the heart - for example, angina. During angina, the heart lacks blood supply. Attacks are aggravated by high physical or emotional stress.

The pain during angina is specific: it can occur suddenly and also disappear after a while; there is always a direct link between emotional and physical overload and the subsequent onset of an attack. Nitroglycerin is able to relieve painful sensations within a few minutes after taking it “under the tongue”.

Angina makes itself felt at any physical activity: weightlifting, walking up the hill, when walking, burdened with a burden. Angina pectoris needs medical supervision, so consulting with a doctor is a must for any patient.

Aortic aneurysm

If a woman has breast tissue in order, then pain in the left breast can be associated with various heart diseases.

A heart disorder such as aneurysm is considered to be quite common. In the United States each year, out of a total number of people who died, 24,000 died from a ruptured heart aorta. So, how to notice in time the symptoms of aneurysm?

When the left chest is very sore, but it is not constant, but with seizures it can be a sign of any blood circulation disturbance in the heart, including the development of an aneurysm. In this case, the pain is felt not in the mammary gland, but as if behind the sternum. These attacks are accompanied by general weakness and blanching of the skin.

A detailed examination by a cardiologist will help confirm or deny this diagnosis.

Often women fear that chest pain may be a sign of cancer. However, if there are no seals in the mammary gland, and no discharge from the nipples occurs, there is no need to worry about it: the fact is that pain is characteristic of the last stages of tumor development, but if there were no complaints before, then there is no need to sound the alarm .

It is quite another thing if the left chest hurts when pressed, and you can feel the seals in this area with your fingers. An additional unfavorable symptom is an increase in the lymph nodes under the armpits and the discharge of fluid from the nipples during squeezing. In this case, there is no need to postpone the visit to the mammologist, because it is well known that cancer in the early stages is successfully treated.
