@NielkRapid change in blood pressure?
Hi Nielk,In the past week, I am experiencing a sudden sharp headache when I first stand up. It eases up with time but, I it is quite disturbing.
Does anyone have an idea why this is happening?
Hi Nielk,
I agree with the above posters, it is probably transient postural hypotension. This happens when then venous systems doesn't contract enough to support blood pressure when one first stands up. If this is the problem, sit for 3-4 minutes from a supine position before standing up. In many people this seems to help.

Was pulse pressure normal too? Systolic and diastolic can each be in the "normal" range while being a bit too close together or too far apart.I just took it while standing and it was normal. Thanks.
I think that maybe it's more an issue of not getting enough oxygen. That's what it feels like. Maybe it's the exertion of getting up from a sitting position that causes this?
