Hi Michelle,
I hope your son is feeling better and things go well at the Drs. hopefully you will be able to find out what's going on. A few yrs. ago I broke out with a terrible rash and had to see a dermatologist (skin specialist) who did a skin biopsy on me and found out I was allergic to the drug (lamictal) I was taking for my seizures. I wasn't in any pain just a lot of itchy skin with a rash. I had to go off the drug immediately.
If you're interested here are a couple of website to help you learn more about epilepsy and different types of seizures and treatments.
www.epilepsy.com

(when the main page come up click on epilepsy and check out all the info. or you can just do a search.)
Here's wishing you and your son the best of luck and May God Bless You Both!
Sue
