Ive had 18 seizures since thanksgiving of 2011. I'm 36 yrs old first time ever going through this. But every time I get a cat scan they can't find nothing now I'm experiencing a old metal taste in mouth and bad headaches all the time. My husband wanted to know what is the white foam that comes out my mouth and nose and how to keep me from biting my tongue and why I can't remember and now off balanced a lot. How can I find out what's going on and what causes this?

Have you seen a neurologist about this?
