my years of fissue (in the same spot) turned into a fistula with an absess and I had to have surgery. Antibiotics only help me. The antibiotics calmed my gut down. I got a fissure from going to the bathroom too much and too much pressure/cramping when I was going.
Cipro/Flagyl at the same times helped, Rafaximin finished up the healing .
If I eat bread, sugar, dairy of any kind whatsoever my symptoms are a ALOT WORSE.
Sugar and Bread are a NO NO for me. I'm not perfect so that tells you I cheat and I pay for it :(
Also I was DX with UC for 10 years and went to Mayo they said because of my history with fissures and fistula they dx with Perianal fistualizing Chrons disease.
Really though, is there much difference? I don't have small bowel ulcers or anything, just all in my Large colon, rectum
Best of luck.
