This is usually seen in women when there is mastitis or mastopexy. 1. Mastitis: usually caused by milk stagnation during lactation, bacterial infection, decreased immunity, trauma to the breast, etc., causing inflammatory reactions to the breast local swelling and pain. During breastfeeding, you should pay attention to the emptying of milk to avoid stagnation in the breast, to prevent bacterial infection caused by trauma to the breast, to clean the skin of the breast regularly, to massage or apply hot compresses locally to relieve pain, and if necessary, to use anti-inflammatory drugs for treatment as prescribed by the doctor. If non-lactation mastitis is caused by breast tuberculosis, blocked milk ducts and other problems, it can occur in both men and women, and can be treated with the appropriate non-steroidal anti-inflammatory drugs, such as ibuprofen, indomethacin, etc. It should also be treated for the cause of mastitis. 2. mastopexy: mastopexy can also lead to symptoms of pain when the breast is pressed, but not when it is not pressed. Due to abnormal estrogen levels, periodic breast pain can occur. It is related to poor dietary habits, irregular work and rest, and emotional depression, and generally does not require special treatment. Adjusting the diet and lifestyle, maintaining a good state of mind, staying happy and avoiding mental stress may improve the condition as estrogen levels stabilize. It can also be treated with medications that clear heat and remove toxins and blood stasis.
