I have had a laproscopic ovary and tube removed one week ago today. I have three small sites. The left one where my ovary was taken is hurting me very bad. It has a pretty good size knot under the skin. about the size of a plum.. its hurts bad. like a stabbing ache..what could this be????? its not comfortable and the percocet i am taking is not helping me any more. i was not in pain til this happend.????any idea what this could be?
