I have been poked, prodded, and darn near disected..My symptoms started 9 years ago and I have had unexplained severe anxiety attacks, irregular heart rate, all of a sudden low blood pressure, digestive problems, dizziness, and the different symptoms come in a cluster at different times, I have heard that I may need to seek help for Dysautonomia, or MSA, how is this diagnosed? How do you know the difference? help please, I have been treating myself for 9 years and had to stop eating gluten, wheat, lots of carbs and be very careful at what I do eat, and exercise daily or I dont feel good...I know MSA is deadly but again how do I know the difference and my doctors, they dont know much about these.
