Absolutely bring it up with epileptoligist. (Glad you got an epileptologist for him)

In the past yr. I had to do the botox, cause I had bad migraines but after doing that the migraines went away. The only time I get them is when I'm to stressed or very upset. As far as the muscles I have developed arthritis because of the nerve problem I have cause of my seizures.

I've also been on it awhile. I take it at night cause of the sleepiness. But it is a useful drug
