Me! And orthostatic hypotension to go with it.
@kevinfitzgerald with pots it tends to be a lot longer than a few seconds. Sometimes you stand up and you literally fall over. On my really bad days, when I change posture I get this ‘aura’, and I can’t hear or see for a few minutes. I have constant shortness of breath and tightness in my chest, and walking, especially stairs, it feels like there is no oxygen getting to my thighs. Sometimes I stand up and I instantly need the loo, because of a blood pressure drop, apparently. When I breathe it feels like I can’t reach the bottom of my lungs, like there isn’t enough strength in my chest muscles to stretch far enough.
Sorry for being boring! My point was that you don’t need to worry - if you had it, you’d know it!
