BS,
Everyone has their own comfort level with medical treatment but in my mind the IBD patient’s primary concern should be choosing a treatment that will be effective and a secondary concern should be side effects. I would never not try a potentially effective treatment due to a fear of a side effect. The only thing you have to fear is fear itself, to quote Franklin Roosevelt, and fear shouldn’t drive treatment. Maybe Remicade will cause side effects and maybe not, if it does you deal with it. If you don’t treat the Crohn’s, and you sound fairly young, you will have problems down the road and have to have surgeries. That’s not what you want. I have had IBD for 46 years and I always tried to treat it as aggressively as possible, and let the chips fall where they may. You sound a little gunshy about biological drugs, but if you haven’t taken them it’s an empty slate and there is no basis for the fear until there is a basis for it.
Good luck-
