Since December I've had an intense pain in my lower right side. It sometimes gets very severe. I cannot do simple things like walk very far, ride my bike, have sex, etc. I've been on the Deprovera shot for almost two years and am thinking of going off of it to see how it affects the pain. The doctors don't know what it is, but it is possibly endometriosis or a rare appendicitis. All tests have come back negative, I even had a laperoscopy. What do you recommend? Has anyone experienced something like this?
