What causes intermittent pain in a woman's armpit?

Generally, intermittent pain in the armpit area in women may be caused by factors such as tight undergarments causing friction, emotional stress and anxiety, axillary lymphadenitis, infected sebaceous cysts, or mammary gland hyperplasia. If discomfort occurs, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. The specific causes are analyzed as follows:

1. Friction from Tight Underwear

Underwear that is too small or made of rough material can continuously compress and rub against the skin and soft tissues of the armpit, leading to localized pain. Switching to loose, breathable cotton underwear and avoiding overly tight styles, along with keeping the armpit area clean and dry, can help alleviate symptoms.

2. Emotional Stress and Anxiety

Emotional fluctuations can stimulate the sympathetic nervous system, increasing sweat gland activity and muscle tension in the armpit, resulting in episodic pain. Practicing deep breathing, taking walks, ensuring adequate sleep, and avoiding prolonged mental stress can help relieve symptoms.

3. Axillary Lymphadenitis

Bacterial infection of the lymph nodes leads to inflammation, causing swollen and painful lymph nodes, often accompanied by redness and swelling in the area. Antibiotics such as amoxicillin capsules, cefradine tablets, or roxithromycin dispersible tablets may be used as directed by a physician. Avoid pressing on the affected area and maintain a light diet.

4. Infected Sebaceous Cyst

Blockage of sebaceous glands in the armpit leads to cyst formation, which becomes painful when secondarily infected. A palpable subcutaneous mass may be present. During the infection phase, topical treatments such as fusidic acid cream, mupirocin ointment, or clindamycin gel may be applied as prescribed. After inflammation is controlled, surgical removal of the sebaceous cyst may be considered.

5. Mammary Gland Hyperplasia

Hormonal fluctuations cause overgrowth of breast tissue, with pain sometimes radiating to the armpit area. Symptoms typically worsen before and after menstruation. Medications such as Xiaoyao Pills, Rupixiao Tablets, or Xiao Jin Pills may be taken under medical guidance. Maintaining emotional stability and undergoing regular breast examinations are also recommended.

In daily life, choose properly fitting undergarments to avoid friction; learn to manage emotions and maintain a positive mood; practice good hygiene in the armpit area to prevent infections; maintain regular sleep patterns and avoid staying up late; and undergo routine breast and armpit check-ups to detect and address issues early.
