brutesky1, I feel for you and have similar autonomic, gastric and heart related maladies. I too am wondering what kind of doctor to go see next. I have an electrophysicist and had another one that retired, and they by and large don't impress me with knowledge about what to do with me.My family doc. seems to know as much except he doesn't have the tools at his disposal that the ep's do. I have a peripheral neuropathy too and have much better luck getting a handle on that, but with the autonomic thing it just seems to me that there are very few truly qualified physicians out there. the two electrophysicists ive had admitted to me that they knew just a little bit, and my top rated neuro didn't want to touch my autonomic problems, he sent me to the ep's. lol I think my immunoglobulin infusions for the peripheral neuropathy help my autonomic problems more than anything else, I say this because I had some breathing problems and the infusions helped with that. just my opinions though.
