Breast distention pain can be treated with dandelion, but the effect is not significant. This is because there is a clear relationship between breast distention pain and breast hyperplasia. Generally, we can treat it with traditional Chinese medicine. By soothing the liver and regulating Qi, and harmonizing Chong and Ren meridians, we can relieve the distention pain. Endocrine treatment can also be used, preferably avoided, but it can be administered before menstruation when the pain is very noticeable in the pre-menopausal period, because endocrine treatment can increase the risk of endometrial cancer, therefore regular pelvic ultrasound examinations are necessary. Vitamin therapy can also be used. Vitamins B, C, and E improve liver function, regulate sex hormone metabolism, and improve autonomic nervous function, and can be used as adjunctive medication for this condition. Vitamin E also has a pain-relieving effect.
