An abrupt involuntary contraction of a muscle that is associated with pain and can occur even when the muscle is at rest.
A sudden contraction of a muscle.
Persistent involuntary tightening of one or more muscles, usually causing pain from excessive rigidity. Muscle spasm may be caused by a strain, injury, fracture of a related bone, or chronic overuse of a muscle. It may also be due to a muscle’s protective action in the prevention of movement of a body part that is stressed. Pain-relieving and antispasm medications may be prescribed; physical therapy may be helpful.
