Hello All, I am wondering if anyone out there has Orthostatic Hypertension. I have many many issues, but specifically I just saw Dr Barboi at NORTHSHORE Neurological Institute in Chicago, and he diagnosed me with Adrenergic Hypersensitivity. He says that I have very low vagal tone and overactive sympathetic nervous system. I think he was actually caught off guard that my blood pressure went up instead of sinking like a normal POTS patient. Any input would be appreciated.
