Dysmenorrhea is pain for 1-2 days. It is normal for women to have small abdominal distension or vague pain on the first day of menstruation, and it will gradually disappear on the second day. Some women have more severe dysmenorrhea, with unbearable pain on the first day of each period, accompanied by nausea and vomiting, which can be diagnosed as dysmenorrhea, and the duration of dysmenorrhea is 1-2 days. Very severe dysmenorrhea requires painkillers to relieve. There are primary dysmenorrhea and secondary dysmenorrhea. Primary dysmenorrhea has no clear cause and will be relieved after the birth, while secondary dysmenorrhea is treated by finding the cause and treating the symptoms. Women should not get cold during menstruation, do not eat cold food before and after menstruation, and pay attention to the protection of Yang Qi. Chinese herbal medicine is very effective in treating dysmenorrhea, and can treat dysmenorrhea by regulating the body’s Qi and blood.
