Most of the lumbar pain during menstruation is caused by pelvic inflammatory disease, adnexitis, or lack of attention to keep warm, causing cold in the waist and abdomen. If occasional menstrual lumbago occurs, it is recommended that you can boil water with brown sugar and motherwort to relieve the symptoms. At the same time, you need to pay attention to rest and avoid overexertion, and pay attention to eating light, easily digestible, high vitamin and high nutrition food, and avoid spicy and stimulating food. If you have regular menstrual back pain, it is best to visit a gynecologist for a specific examination to confirm whether you have pelvic inflammatory disease or adnexitis, so that you can get the right treatment in time.
