The reason why women have painful menstruation may be due to poor outflow of menstrual blood because the uterus is not well developed or the cervical canal is narrow, or it may be caused by strong contractions of the uterus during menstruation. Some women get nervous when they have their period and are afraid of stomach pain, which in turn can cause dysmenorrhea. There are also genetic factors, such as if the mother has dysmenorrhea, the daughter may also have dysmenorrhea. Some women will have backache and abdominal pain, cold hands and feet, pale face and vomiting when they have menstruation. You can drink more warm water and brown sugar water to relieve the symptoms when you have menstrual pain, avoid eating cold, spicy and stimulating food, and pay attention to more rest and less fatigue.
