I was diagnosed with crohn's disease in my large intestine.Recently i had fissures.
I had my LIS almost 5 months ago.But still i feel a huge bulge in the anus,and it sometimes bleeds.
I feel like this is not the fissure, because fissure pain was different.
so, i have a doubt as to whether this pain and bleeding is being caused by something else or
is it the fissure coming back again.?Any help would be greatly appreciated.

Do get in contact with the surgeon who did the surgery and say what pain you are in. Don't just leave it as it could be an abcess and that will not go away on its own. Sorry you are having trouble, but as you have Crohn's I don't think you should just accept it. Let us know and take care.
