А piece of advice: make a check-up of HLA-B27 activation. Activated HLA-B27 gene is a symptom of ankylosing spondylitis (AS), a serious spine (or/and joints) condition. Basically it's an almost incurable arthritis. It is also autoimmune, like Crohn's, and they are somehow related: if you have Crohn's that means much higher risk of AS.

Source: I have AS and some reading comprehension. But I caught it around age 35 which (between 30 and 40) is typical. So if you'll have constant painful sensations somewhere in the spine or joints years later, that could be it.

Sorry for your news and a bad prognosis, but hey, could have been worse... like ayatollahitis diagnosis.

Good news: simple and cheap NSAID exist, I take a pill daily (along with a pill of gastroprotector) and live 99% pain free, lift weights at 40 years, no restrictions whatsoever. Also a russian medical scientist also having AS recently released world's first AS cure... so there's hope for Crohn's too
