"Not satisfied with my neurologist"

I have seen a neurologist at this hospital on a number of occasions for head pain and numbness of the mouth. He has done a brain MRI over 2 years ago, which was non conclusive and has done nothing ever since. While the pain gets worse and the numbness is constant, he just sits there and says he doesn’t know what it is and that he’s only a little old doctor. He even called himself stupid, which is the only intelligent thing I have heard him say.
