Hi my son (12) has crohn's. He is on azathioprine and has recently finished a modulen diet. He is complaining today of abdominal pain and sickness. He also has pain in his upper digestive tract ( he had ulcers all through him from his oesophagus to his small bowel show at the time of his diagnosis). He is also complaining of having to pee every fifteen minutes or so, it is not painful to go but his lower abdomen is very sore when he gets the urge. My question is is that a symptom of crohn's or it is something else and is sickness a symptom? Does the fact that he has a mouth ulcer indicate a potential flare? Are these pains something he has to live with or do they mean the meds are not controlling things as well as they could? Thanks if you have taken time to read this and have any advice.
