Many women have headaches during menstruation. The causes of menstrual headaches may be: 1. The hormone level in the body changes during menstruation, and the estrogen and progesterone in the body are low, which will lead to neurovascular abnormalities, thus causing headache symptoms. 3. If a woman has a long-term deficiency of essence and blood, it will cause headache, and if she is under too much stress and too nervous, it is easy to have liver qi stagnation, thus causing menstrual headache. If the headache is not serious during menstruation, you can rest more, but if it is more serious, you can go to the hospital and use nerve-nourishing drugs under the guidance of the doctor.
