Muscle Cramps
Alternate Names : Cramps - Muscle
Definition
Muscle cramps are involuntary and often painful contractions of the muscles which produce a hard, bulging muscle.
Muscle twitching (fasciculation) is the result of spontaneous local muscle contractions that are involuntary and typically only affect individual muscle groups connected to (innervated by) a particular motor neuron. This twitching does not cause pain.

Overview & Considerations
Ordinary muscle cramps are common and may be stopped by stretching the affected muscle.
Muscle twitches are minor and often go unnoticed. Some are common and normal, while others indicate a neurologic disorder.
