Hi and welcome to the forum! I think your doctor will want to know about all of your concerns, certainly. I do not know if you have had a stroke, but clotting is something we see a fair amount of (do you have the free brochure from the http://www.POTSCare.com site? That may be helpful. I don’t know if you have seen our findings concerning a propensity for high intracranial pressure causing many neck symptoms (and other issues), but it is worth considering, too. Do you have The Driscoll Theory book that explains this? 🙂
