Thanks everyone for your input. I have been through several different kinds of meds. My doctor, after exhausting yet another idea/med, feels his hands are tied and would like the additional testing, ideas and experience that an autonomic lab could offer me. He has tried almost everything and really is awesome. He handles colds and such for me even though he is a cardiologist. He still knows more about what a cold, flu, etc. can do to a person with POTS. He reads a lot, but knows when he needs to ask for help. The initial evaluation tests for this study would be enough to at least give us a better idea of where I am at autonomically. He sent the information for me to be seen by them as a consultation, but I was put into this study instead. In the long run I am hoping that it will be of a greater benefit. Not just to me, but to the whole autonomic community. Ellyre your story sounds very much like mine. It is nice to hear from the rest of you who have also been waiting so long to get into NIH. At least now I know that this is the norm.
