Do you live near Dr. Driscoll? She could probably get to the bottom of some of your problems. If not, is there an autonomic specialist in your area? A cardiologist doesn’t always know a lot about dysautonomia.
Start with viewing the videos that are on this website. There is also a brochure on potscare.com that you can download for free that gives you good information to start with. Last but not least, Dr. Driscoll has written a book “The Driscoll Theory” that has an enormous amount of information on how to help yourself. I highly suggest you purchase it if you can. You need to get to the root cause of your autonomic dysfunction. There is hope. I wish you the best.
