If it is sometimes caused by crohns/fistulous crohns? I am feeling the worst pain right now, in the exact spot where I had an ovarian cyst the size of a golf ball about removed four years ago. The thing is they had no idea it was there, until they did the ileosectomy and located and removed it during the surgery. Anyway, I was able to differentiate that pain from crohns pain at the time but doctos did not listen since they figured it was appendicitis, which i had, but I can tell the difference where my ovaries are. I am getting a pelvic xray or something for it. I have a fistula already....anyway I just also want to know if there is any use in taking tylenol for this sort of pain, and if any other crohnies have had to deal with this additional sort of burden?
