I have endometriosis, and history of ovarian cysts. 44yrs old. This is unusual for even me. Menstrual cycle started three weeks ago. Constant, sometimes severe pain on right side by ovary. I have had many cysts rupture in the past, pain is somewhat different. Area is warm, at times can feel a lump. Difficulty walking at times. Constant pain. Advil, Tylenol, etc have no effect. This is a CRAZY question, but what about applying a small amount of topical menthol. Also, heat nor ice packs have been helping.
