My 21 year old son has had three seizures. The first one occurred Thanksgiving 2010, the second one occurred in January 2012 and another one today. Each time he doesn't remember what happened, he is very disoriented immediately following with vomitting, soreness in his leg muscles and he has biten his tongue. Each episode is followed by a bad head ache. I have asked him if he can remember anything he had done or ate different from his norm and each time he just tells me he hasnt eaten or had anything to drink for a prolonged period. His paternal grandmother was diagnosed with epilepsy several years ago. He has no insurance and we have no money for a nuerologist and all the expensive testing. I really dont know what to do but I feel like this is an urgent matter. I would just like to know is there an underlying cause that he can try to avoid?
