I experienced a thigh cramp the other day while diving. Now I have occasionally cramped in a calf muscle, but had never had the thigh go like it did. We were searching for moorings in the bay, so it wasn't very deep, less than 20 feet. The water temp was 49°F and I was diving wet and had been in the water for a while, but was not cold or uncomfortable, hands and feet and everything were fine. Anyway, the cramp totally immobilized me and I could not get it to ease, so I inflated my BCD and surfaced and tried to float comfortably until the boat got to me. Once aboard, I found standing with weight on my leg helped ease the cramp. It hasn't happened since, but I was wondering if anyone knew of some way to ease a thigh cramp while in the water, like pulling on the fin tip for a calf cramp?
