Good luck!!! And if he's a physician with any heart whatsoever, he will not mind your seeking a second opinion, which you deserve. And you deserve the kind of treatment that you can get at Barnes-Jewish (which, from what I understand, is absolutely stellar). You have no obligation to someone who might or might not keep you in pain for the rest of your life.

some of it's magic
some of it's tragic
but i had a good life all the way......
