Introduction
In general, mild pain in the armpit may be caused by muscle fatigue after exercise, hormonal changes during the female menstrual cycle, folliculitis, lymphadenitis, or mammary gland hyperplasia. Treatment under a doctor's guidance may include general management and medication. It is recommended to develop healthy lifestyle habits and maintain a proper balance between work and rest for better overall health.

In general, mild pain in the armpit may be caused by muscle fatigue after exercise, hormonal changes during the female menstrual cycle, folliculitis, lymphadenitis, or mammary gland hyperplasia. Treatment under a doctor's guidance may include general management and medication. Specific analyses are as follows:

1. Muscle strain after exercise

Intense physical activity or prolonged use of the upper limbs may lead to fatigue in the muscles and soft tissues of the armpit area, causing mild discomfort or pain. Appropriate stretching exercises can help improve blood circulation and accelerate muscle recovery.

2. Changes during the female menstrual cycle

Fluctuations in estrogen and progesterone levels during the menstrual cycle may affect breast tissue and the lymphatic system, leading to discomfort in the armpit region. It is recommended to wear well-fitted bras and avoid clothing that is too tight or compresses the armpit area.

3. Folliculitis

Folliculitis is an inflammation caused by infection of hair follicles, commonly due to Staphylococcus aureus. The inflammation can stimulate nerve endings in the armpit, resulting in localized dull pain. Symptoms often include redness, swelling, warmth, pain, and sometimes purulent discharge. Patients may use fusidic acid cream, mupirocin ointment, or cefuroxime axetil tablets as directed by a physician.

4. Lymphadenitis

Lymphadenitis is an inflammatory condition of the lymph nodes triggered by bacterial or viral infections. Inflammation may cause lymph node enlargement and pain, leading to mild armpit discomfort, possibly accompanied by systemic symptoms such as fever and fatigue. Medications such as amoxicillin capsules, cefradine capsules, or penicillin V potassium granules may be used under medical supervision.

5. Mammary gland hyperplasia

Mammary gland hyperplasia results from abnormal development and regression of breast tissue. Hyperplastic tissue may compress nerves in the armpit, causing dull pain, along with symptoms such as breast swelling, tenderness, or nipple discharge. Under medical guidance, medications such as Ruxiaoxiao capsules, Xiaorusanjie capsules, or Runing granules may be used to relieve symptoms.

It is recommended to maintain healthy lifestyle habits, balance work and rest, and avoid excessive fatigue to promote overall health.
