Sorry to hear about all that. I had ulcerative colitis or chrons. They were never sure which. It all went away after got a liver transplant. To tell the truth, I think the colitis/chrons was mis-diagnosed and was only a symptom of other much more serious things which really were the problem to begin with.
You should not worry. Your diagnosis is common and usually easily treated with antibiotics. Best of wishes and luck for you.
The old timers would just swallow a charge of powder, suck down a canon fuse spagetti style, and light it off. The burn out took care of all that ails you!
