Is is Crohn's Disease or something more?

Ive had crohns disease for 8 years and all of his symptoms you're describing are pretty typical.Crohns never goes away,it just goes into remission.He needs to get back on something and NOT stop.Just because he feels better doesnt mean he is.Making a food diary could help him see what foods he should maybe stay away from.Lettuce is horrible on my stomach! Also,with the aching joints,its possible he could have rheamatoid arthritis(the two go hand in hand) Knowone in my family had crohns either,it CAN be heridatary,doesnt mean it is.The fevers mean he has an active infection and he needs to do something about it before something serious happens,like a surgery that would require a POOP BAG!
