A cramp is a sudden, involuntary, painful skeletal muscle contraction [1] [2] or overshortening associated with electrical activity; [3] while generally temporary and non-damaging, they can cause significant pain and a paralysis-like immobility of the affected muscle.
This meaning implies that the primary defect is within the muscle, as opposed to the nerves ("neuropathies" or "neurogenic" disorders) or elsewhere (e.g., the brain). This muscular defect typically results in myalgia (muscle pain), muscle weakness (reduced muscle force), or premature muscle fatigue (initially normal, but declining muscle force).
Dead legs and charley horses are two different types of injuries: A charley horse involves the muscles contracting without warning, and can last from a few seconds to a couple days. A dead leg often occurs in contact sports , such as football, when an athlete suffers a knee or other blunt trauma to the lateral quadriceps causing a haematoma or ...
Myalgia or muscle pain is a painful sensation evolving from muscle tissue. It is a symptom of many diseases . The most common cause of acute myalgia is the overuse of a muscle or group of muscles ; another likely cause is viral infection , especially when there has been no injury .
A spasm is a sudden involuntary contraction of a muscle, [1] a group of muscles, or a hollow organ, such as the bladder. A spasmodic muscle contraction may be caused by many medical conditions, including dystonia. Most commonly, it is a muscle cramp which is accompanied by a sudden burst of pain. A muscle cramp is usually harmless and ceases ...

Electromyography (EMG) may show particular patterns in specific muscle diseases; for instance, McArdle's disease and phosphofructokinase deficiency show a phenomenon called cramp-like contracture. [18] There are genetic tests available for many of the hereditary muscle conditions that predispose to myoglobinuria and rhabdomyolysis. [12] [13]
The term "fibromyalgia" was derived from Neo-Latin fibro-, meaning "fibrous tissues"; Greek μυο- myo-, "muscle"; and Greek άλγος algos, "pain"; thus, the term literally means "muscle and fibrous connective tissue pain". [20] Thus arguably this term is inaccurate and misleading, as it only reflects a part of the syndrome symptom set. [21]
