Hi Ginger, I have just read your post to Miriam offering to ask questions on our behalf. I would have some questions that I would be curious to find an answer or a hypthesis. I would like the answers to be as medicaly technical as possible. 1- With hyperadrenergic POTS, ie adrenaline x20 to x100 above the norm and noradrenaline about x5 above the norm. What could be causing muscle weakness, pseudo myotonia and pseudo periodic paralysis? 2- What medication would help with this muscle problem? (I already am on: propranolol, proamatine, salt tabs) 3- If he has no idea, what specialist should I see, other than neurologist? Thank you very Ginger for your offer. I will probably never be able to go to Mayo because my government does not pay for out of country care. I appreciate that you take some time for me. Ernie
