Gosh, what a terrible thing has happened to you. You are not supposed to feel pain these days, with the drugs they give you. I am shocked to hear of your experience. What's worse is the doctors and nurses who attended you did not DO SOMETHING right then and there as a result of your pain.
Either they didn't give you enough drugs, or they may have even torn some tissue, is my thinking, especially since you are still uncomfortable a day later.
