Hope that never happens to you again! I haven't had as much experience with muscle spasms as some folks here have, but I've had enough to know I'd do almost anything to make it not happen!!

I have to be really careful not to have blankets tight over my toes when I lie on my back, or they cramp up like crazy. Once my toes cramped up, and when I yanked my foot up to try to rub out the cramp, my thigh muscle spasmed. Hurt so bad I nearly barfed. Holy cow.

Are you taking any meds for it? (Sorry if that's a repeat question)
