electrocuted now I have horrible headaches non stop

I was electrocuted in my home in April of 2007! When down power lines in my back yard some how electrocuted me standing in my kitchen talking on a land line phone. After the current realeased me I fell to the floor convulsing , siezing, and was unable to breath. I was uncontentious and barely remember anything but my wife witnessed the whole thing and saved my life. I am thankkful to God to be alive but now I suffer from one constent HORRIBLE HEADACHE every since that day. What do I do? I am seeing a neurologist and they say that I probaly have nerve damage in my brain. And that I do now suffer from dysautomia.They also say that there is not really anything they can do for me but medicate me and there is no way to tell if I will ever heal at all! I am on 80mg Oxycotin ER with a break through 30mg. oxycodone in between doses, but now it seems like those aren't even giving me relief. I am suffering a great deal , just about 24 hrs. a day, with few 2-4 hours here and there with any real comfort. They say that can't give me anymore medicine and I basically have to deal with the pain. Easy enough for them to say when they are not the ones that feel like their dying. I am only 28 years old and I feel like that day stole my life as well as my wife. Help me I can not live like this the rest of my life. What do I do? - Brian
