Thanks for the response. I have heard of Chiari Malformation and have briefly researched it more out of curiosity. I did check out the link you sent me. While some of the symptoms may sound somewhat like the symptoms I have I really don't think that it applies to me. But I will read a little further on it just to make sure. And the doctors that I have been I really have a great deal of confidence int as well. I think if it was chiari malformation they would have caught it. Thanks again for the input.
