All of your symptoms are the same ones my son had/has. He has POTS. You need to find a specialist who has knowledge about the autonomic nervous system/dysautonomia's.
Like the post above Dinet.org is a very good website with a very active forum.
Thank you very much :) prayers to you as well!
I can't begin to imagine what you are going through as a teen and having these bizarre symptoms. I am 56 and can no longer work due to spinal disorders, surgeries, and what I think is some form of dysautonomia, also.There is a website:dinet.org,that is helpful and a doctor in Pensacola FL who has POST and runs The Center for Autonomic Disorders, Prayers and blessings to you in your search for knowledge and help, my dear!
