Doctor - What is the best remedy for a knee muscle cramp?

Treatment of a Muscle Spasm

When muscle cramps occur, there are several things you can do to help ease them, such as massaging, stretching, or icing the muscle, warming the muscle, or taking a bath with Epsom salt.

For a charley horse in the calf or a cramp in the back of the thigh (hamstring), try putting your weight on the affected leg and bending your knee slightly, or sit or lie down with your leg out straight and pull the top of your foot toward your head. For a cramp in the front of the thigh (quadriceps), hold onto a chair to steady yourself and pull your foot back toward your buttock.
