I have a dx of Giant cell vasculitis of the brain. My BP is quite high when sitting or standing (roughly 200/100) and normal (roughly 125/60) when lying down. I have real problems with headaches, even worse when my BP is normal rather than high. Several years ago I had a stroke in the right pons, before getting the vasculitis dx. I am intolerant of steroids and NSAIDS. I would like some explanation if you have one. All I find is information on postural hypotension. I have postural hypertension.
Hi, Thank you for posting your query. Postural hypotension is most likely related to side effects of the blood pressure medications. Please send us a complete list of medications that you are taking at present. If medication as a cause is ruled out, then, we need to exclude autonomic dysfunction as a cause of postural Chat Doctor.  There are several bedside tests that a doctor can perform to exclude a diagnosis of autonomic dysfunction. I hope it helps. Please get back if you require any additional information. Wishing you good health,
