Hey Guy! At least you know what's going on. When I was your age I was just having "stomach prolems" occasionally. It took until I was almost 43 to find out I has "something wrong". There are great resources here if for no other reason than the sympathetic ear. No one here will say, try pepto, you eat crappy foods and your lifestyle is doing this to you, so on and so forth. Vigilance and education and support will help you make it through. I have my own rant thread (probably page 2 or 3 by now) and we all need that once in awhile.
Talk to your GI about Bentyl for help with the cramps and if your insurance will cover it, Entocort, which is a glucocorticosteroid, made specifically for the digestive tract. It has none of the problems of Pred.
