So, how do you know if you have an abcess or just a sore spot. My rectum area is very sore. I am using the suppositories right now, and I can feel a sore spot. WHen the stool hits that area--it hurts. I just started 6mp, last week. Does 6 mp help heal those things? Or could it just be the crohns making it sore. I am on 20 mg of pred and well...it still hurts...Mmmmm
