My son was first diagnosed with Crohn's 5 years ago. After taking prednisone initially and then imuran continuously ever since, he has not had any major symptons. Is it possible that it may not flare up again since he has been pretty much sympton free for about 4 years? Or is it more a case of 'when' not 'if' it returns and are future episodes progressively worse? We have narrowed it down to milk which appears to be the main culprit and providing he stays off of that, he seems to be OK. My son is 18 and naturally enough wants to lead a normal life, and is convinced he will not have another episode if he stays away from milk and wants to come of the medication. I am against this idea, as is his doctor, although his previous doctor said he would think about taking him off medication if he was incident free for 2 years. I would be grateful to hear from anyone who has managed to remain in remission for many years without medication.
