If you look at the side effects of 6MP listed on this site, you will see all of the symptoms you listed.
http://ibdcrohns.about.com/cs/prescriptiondrugs/p/med6mp.htm Because these symptoms started soon after starting the medication, it is logical to think that the med is the culprit. about
the only way to see if the medication is the culprit is to stop the med. I'm not saying that is what you should do, but I do think you need to discuss this with the doctor. I seem to recall that the dosage for 6MP is something like 1.0 to 1.5 mg per kilogram of body weight in adults. I am not sure if that is the same for children.
