EXTREME CRAMPS

So I get really bad cramps. I can’t tolerate any BC so that can’t help relieve pain. I’ve had laparoscopic surgery done to check for endometriosis but there was none (thankfully). However we have no idea why I’m in so much pain. I kid you not I took a Percocet an hour ago left over from my gall bladder surgery in December, and I’m STILL in pain. Nothing works it seems and it’s debilitating to the point that I laid on the bathroom floor this morning because it hurt too much to move. What should I do? I’m only 19 so hysterectomy is not an option.
