How can you relieve a persistent leg cramp?

Question

I'm having a really painfully leg cramp each time I sit down. It starts with the thigh and quickly hurts the calf. It streches all the muscles in my left leg and I start to sweat and breathe heavily. I can't sit for more then 2 minutes before I need to lay down.

Has this ever happened to anyone before and have you found its remedy?

Answer 1

Yes, I've had that and I researched it and found a simple cure.  Potassium. You can get it over the counter at grocery stores and health food stores.  You can't overdose on it.  When I get a leg cramp I take 4 of the 99mg  pills.  If this is an ongoing problem for you just follow the directions on the bottle for preventative measures.

Answer 2

Water.  Drink lots of water.  

You can't overdose on it. <---PLEASE DO NOT LISTEN TO THIS.  Every pharmacist I have ever asked about potassium says that it can be very dangerous in high levels.
