I'm not really sure, but I guess the best thing to do would be to be honest. I don't know what your situation is exactly, but perhaps you could use some help? Your doctor will most likely be concerned and may refer you to a p-doc or something. Your primary doc in the meantime might give you something to help heal the wounds and prevent scarring. The important thing is your health, physical and emotional. If I may, I imagine you have dealt with SI for a while now, and you deserve to be free from it. It may make you feel better but it can't really help you. Your doctor is most likely a caring person who will understand how to help you. Let them! You have the support of us PC peeps.
