If your stomach hurts when you have your period, the easiest and most effective way to relieve the pain in your lower abdomen is to make a bowl of hot brown sugar and ginger water and drink it while it is hot. Because the brown sugar water not only has the effect of eliminating fatigue and replenishing blood, it can also make the menstrual blood flow more smoothly and relieve the stomach pain caused by uterine contractions. In the case of menstrual pain in the stomach, it is best to find out clinically the cause, whether it is primary dysmenorrhea or secondary dysmenorrhea. Depending on the cause of dysmenorrhea, the clinical treatment is different. If the dysmenorrhea is caused by pelvic inflammatory disease, active anti-inflammatory treatment is required. If the dysmenorrhea is caused by endometriosis, it should be treated clinically with Daphylline or the intrauterine Manned IUD.
