Muscle Cramp
A muscle cramp is a sudden, involuntary spasm of a muscle. Most muscle cramps develop in the leg muscles, particularly in the calf. In addition to a sudden sharp pain, you may be able to feel or see a hard lump of muscle (sometimes called a 'knot') beneath your skin. Muscle cramps usually disappear on their own.
