Well, if I do have P.A.D. I must have a blockage somewhere above or about where the artery forks for the legs, because I get it in both legs.
I noticed yesterday that I got it in my calves when walking up a little hill. That's new. Thank you Thompson.

Strad, I only get cramp from working hard and sweating, and NOT drinking enough water.   Drink enough during the day, and no problem.
Drink lots of salted water when cramp strikes, it is gone in a half-hour.
