Dear Kathy- With the Mention of fistulas it sounds like you might suffer from Crohns Disease as well. Have the doctors ever it? I am on Remicade for Rhuematoid arthritis and it does resolve fistulas.
You might want to read up more on it. You might also look into Naltrexone for pain. I dont like the term the doctor gave you, but it does validate your agony. Hypochondriac to cripple? How much more unenlightened can doctors become. You are in my prayers, Deborah
