One of my doctors said that I have POTS and another one said he didn't know what the heck is going on and did a lot of tests and came up empty. I am on midodrine, florinef, inderal, and depakote er. I just don't know what to do anymore.
It seems you have been to doctors before, as you are on meds. What did they say? What are the meds?
