I had Crohn's in my rectum, anus and colon. From about
1994-1997. (diagnosed in 1982 aged 12) My bumhole was a complete mess, I used to get stuff stuck in it, was gross
Only relief I got was having it surgically stretched monthly. I had a permanent proctocolectomy and an ileostomy in 1997 it was like a new lease of life. Only had one major flare since, Crohn's and a nasty fistula on the site of my stoma, had a revision of my ileostomy in 2002 but since then fingers crossed, only had upper GI probs, possible GERD and gastritis.
Hope you can get some relief soon, I know how you must feel
Best wishes
