Symptoms of adenomyosis include secondary, progressive dysmenorrhea and increased menstrual flow, with some patients experiencing prolonged periods. Patients with adenomyosis often experience back pain in the lower back and lateral lumbar eyes, and even back pain and swelling. Through rest or localized hot compresses, it can often be improved, and with the passing of menstruation, the back pain will also be slowly relieved.
