I was on topamax last year had horrible side effects but the worst was the bruising... I would just bump my knee or maybe wrestle w my kids and soon after there would be actual finger marks!!! I looked abused... I had something dropped on my forearm and had to go to the hospital it was so swollen and black they thought it was broken! only after going off of topamax did I realize that it seemed to be from the drug... my doctor and pharmacist said it couldn't be but just because it wasn't "on the list" of problems it therefore couldn't have been from Topamax... Never have that problem OFF of the drug...
