Why do armpits hurt before menstruation?

Armpit pain before menstruation may be related to factors such as fluctuations in hormone levels, breast hyperplasia, lymph node reaction, mental stress, and underwear compression. It can be relieved by hot compresses, adjusting underwear, and drug intervention.

1. Fluctuations in hormone levels

Elevated levels of estrogen and progesterone in the body before menstruation may stimulate breast tissue, causing slight swelling of accessory breasts or lymphatic vessels in the armpits. This kind of physiological pain is usually accompanied by breast swelling and does not require special treatment. It can relieve itself after menstruation. You can reduce your daily caffeine intake and avoid high-salt meals.

2. Breast hyperplasia

In patients with breast hyperplasia, premenstrual hormonal changes can aggravate gland congestion, and pain may radiate to the armpits. Symptoms include palpable granular nodules and cyclic pain that may be related to chronic stress or endocrine disruption. Doctors may recommend the use of proprietary Chinese medicines such as Rupixiao Tablets, Xiaoyao Pills or Hongjin Xiaojie Capsules.

3. Lymph node reaction

When immunity declines during menstruation, axillary lymph nodes may appear physiologically swollen, showing pain when pressing but no induration. It is necessary to observe whether it is accompanied by fever or persistent swelling to rule out the possibility of infection. Keep your armpits clean and dry and avoid using harsh antiperspirant products.

4. Mental stress

Anxiety can amplify premenstrual body sensitivity, leading to muscle tension or false nerve pain. You can relax through deep breathing training or warm bath. If necessary, use oryzanol tablets under the guidance of a psychologist to regulate autonomic nervous system function.

5. Underwear compression

Overly tight underwire bras may compress axillary lymphatic drainage, especially when premenstrual tissue edema occurs. It is recommended to choose a seamless sports bra, wear it for no more than 10 hours a day, and do a gentle armpit massage before going to bed to promote circulation.

The correlation between pain and menstrual cycle needs to be recorded on a daily basis. If the pain lasts for more than 3 menstrual cycles or abnormal lumps appear, you should go to breast surgery in time. One week before menstruation, you can add foods rich in vitamin B6, such as bananas and oats, to help relieve hormone-related discomfort. Avoid self-administered analgesics to mask potential pathological changes, and all drug use must be evaluated by a professional physician.
