have they diagnosed you yet? if they haven't try not to worry, bowel problems are difficult to diagnose and there are many conditions with similar symptoms. crohn's disease can often get confused with IBS before the diagnosis is made. I know that with IBS gas and pain are major symptoms and the fact that you feel generally well and eating well is perhaps an indicator that you have IBS rather than crohn's?
(obviously unless your crohn's is very mild)
and i'm not sure if every single crohn's sufferer has diarrhea but it would be one of the most common symptoms of crohn's also so maybe the fact you don't have it is a good sign?
i wouldn't worry at this stage until you get your answers, there are many treatments available, some with very little side effects. also, living with the disease, can be hard to get your head around it at first but the way i look at it is everyone at some stage of their life are gonna have some kind of health complaint/ illness, the sufferer just finds a way of dealing with it, there's nothing you can do about it other than not dwell on it, in all honesty its hard not to sit and feel sorry for myself and say 'why me?' at times but the only one that can choose not to feel like that is me and to have the best life possible i just have to be positive.
i hope you get good news! fingers crossed! try not to worry, and welcome to the forum!
