If the dysmenorrhea is caused by abnormal uterine position, certain positions will relieve it. If the dysmenorrhea is not caused by the abnormal position of the uterus, other positions will not relieve the symptoms of dysmenorrhea, such as the uterus is in the state of retroflexion and retroversion, the menstrual blood can not be discharged smoothly and cause dysmenorrhea, you can lie on your stomach to rest on the bed and put a hot-water bag on your waist, to promote blood circulation, so that the menstrual blood flows out more smoothly, and reduce the symptoms of dysmenorrhea. If the uterus is in anterior flexion and anterior tilting position, you can lie on your back and gently press your hand above the pubic symphysis, which will also correct the anterior flexion and anterior tilting position of the uterus, and also make the menstrual blood flow smoother, and alleviate dysmenorrhea. If the dysmenorrhea is caused by endometriosis, pelvic inflammatory disease, or uterine developmental abnormality, the dysmenorrhea cannot be improved clinically with the resting position.
