Those who have orthostatic hypertension with the ME and POTS may be interested in the following. I wonder if orthostatic hypertension is related to autonomic dysreflexia which can appear in MS patients http://en.wikipedia.org/wiki/Autonomic_dysreflexia "This condition is distinct and usually episodic, with the patient experiencing remarkably high blood pressure (often with systolic readings over 200 mm. Hg), intense headaches, profuse sweating, facial erythema, goosebumps, nasal stuffiness, and a "feeling of doom". An elevation of 40 mm. Hg. over baseline systolic should be suspicious for dysreflexia." I fit the BP part and I can break out in a sweat when this happens... and I do freak out (doom feeling can happen.. Im going to pass out if I dont sit down to stop it raising further). Im not sure if I had goosebumps or not when i had the last collapse at shops incident I thought was just POTS (dont know if my BP went up too on that occassion, I suppose it would of done as i was standing). I remember rubbing my arms after that incident and feeling cold (I may of had goosebumps directly after the collapse..during collapse thou I felt flushed). My nasal stuffiness thou i havent noticed in relation to it and rather is a allergy thingy (dust mite allergy i think). anyway with all this.. Im starting to suspect that orthostatic hypertension could be a kind of autonomic dysreflexia. Seeing we do get a lot of things MS patients get (Ive had a ton of MS symptoms over the years) I wouldnt be surprised if some of us are getting this one too.
