Did they list gastroparesis ? I didn't see that one. Regarding gastroparesis I ran into a post by someone named Richard Briseno who developed gastroparesis as part of a collection of symptoms including fatigue, dizziness. It turns out he has coxsackie B (an enterovirus). I wonder if the virus is causing that.
The zyto I had not heard of and I googled it. to be honest, I'm not big on those types of machines. There's really no evidence they work. With your health problems, I think you need more definitive answers. I know I do.
