Just recently realized that BP was high when I take it sitting or lying down.(150-166/88-99)
Systolic always DROPS 15-30 when I STAND UP. But I get a pain in my neck and a bad headache.
Diastolic drops very little, stays the same or rises one or two points.
After the episode, and the headaches go away, the BP returns to normal for a period of time....until I sit down and stand up again....then the headache comes back.
