The last 3 times my son thought he was having a major flare up it turned out he had an infection. Symptoms are severe cramping and bloody diahrea. The first infection we don't know what it was because his GP put him on Flagyl, Cipro and prednizone without doing any testing first. Then it was campylobacter and now C-dif. He takes azathioprine and colozol on a regular basis. For an infection they add in antibiotics and prednizone. If at the end of the course of antibiotics he feels better they don't test to see if it is gone or not. The last time he was scoped was October of 2009 and they said it was clean. The doctor is considering changing to Remicaid. But if I understand it correctly that is a stronger immune suppressant. We wonder if he has had flares or just infections? If it isn't flares why go to Remicaid? Any one else have this type of experience?
