My 18 year old son was diagnosed with active Crohn's in November. He is on Asacol, Aciphex and predisone. He started out on 40mg of the steroids and has got down to 10mg this week. He has started feeling like his body is on fire from hot flashes every couple of minutes. Is this normal? We are new to this and are trying to find out if that is the cause of it or if that is a new symptom from the disease itself. Can anyone give any advice?
