Breast swelling and pain can be treated with hot compresses, but the results may not be very satisfactory. Breast pain caused by mammary gland hyperplasia is generally treated with traditional Chinese medicine, which relieves pain by soothing the liver and regulating qi, and harmonizing the Chong and Ren meridians. Endocrine treatment can also be used, preferably avoided, but can be taken before menstruation when the pain is very significant in the pre-menopausal period. When undergoing endocrine treatment, it is necessary to regularly re-examine the pelvic ultrasound, as endocrine treatment may increase the risk of endometrial cancer. Vitamin therapy can also be used; vitamins B, C, and E can improve liver function, regulate basic metabolism, and enhance autonomic nerve function, and can be used as an adjunctive treatment for this condition. Recently, vitamin E has also been considered to have pain-relieving properties, and regular ultrasound examinations of the mammary glands or mammography are necessary when breast swelling and pain occur.
