Any postural change is uncomfortable
When I get out of bed, I feel dizzy and weak and my headache intensifies, but if I stand for a long time, my organism begins to stabilize, and then I experience the same symptoms as soon as I lie down. It's like blood rushes into my head, overwhelming me. So it's not just orthostatic intolerance, but sensitivity to any change in posture.
Do other people get this too?
