I have Crohns colitis and have just had a flare up but now told I also have a fissure. It is agony, like being knifed every time I have a bm. I have been given Rectalgesic to heal and Instillagel to help with the pain. I’m not sure how long I can cope with this, it is truly agonizing. Anyone else have/had a fissure? Any comfort to offer?
