What are the potential causes of severe, progressive lower back and leg pain that occurs cyclically before and during menstruation, and what are the recommended diagnostic steps when therapies like dydrogesterone, evening primrose oil, and uterine supplements fail to provide relief?
When back and leg pain persists despite dydrogesterone and supplements, it may point to conditions like endometriosis, where tissue similar to the uterine lining grows outside the uterus, sometimes pressing on pelvic nerves. To help find answers, I highly recommend consulting a gynecologist. They may suggest a pelvic MRI or a specialized ultrasound. If needed, a minimally invasive procedure called a laparoscopy is the clearest way to diagnose endometriosis.
