Poor baby....he definitely is having a difficult year. I looked up neurologists in the state of GA and you really don't have a lot of choices. At this point, I would be leaning towards having a MRI done because I like to know what I am dealing with. Treating on a guess is ok for short periods but when the treatments aren't working, I want answers.
