After researching several sites, I compiled a list of symptoms associated with both Neurally Mediated Hypotension and Postural Orthostatic Tachycardia Syndrome. More and more research is being done on a daily basis and I suspect that it won’t be long before this list changes again. When I first got sick the list of symptoms was rather short and seemingly insignificant. It is comforting now to read about some of the postural orthostatic tachycardia syndrome symptoms that I still struggle with and can finally say are associated with my disorder.
