Thanks, stefspad, for this suggestion: "Best advice from my PT: whenever you think of it — whether standing, sitting or lying down — clench your buttocks for five seconds. You can't just think about your feet and hands, you have to consider the source: legs, arms, shoulders, buttocks and spine." This makes so much sense to me. Appreciate it too because with hypotension, I learned that if my b.p. suddenly dropped low enough to make me dizzy, clenching my fists tightly until I could sit down helped the blood circulation.
