Symptoms of neuromuscular disease may include numbness, paresthesia, muscle atrophy, a pseudoathletic appearance, exercise intolerance, myalgia (muscle pain), fasciculations (muscle twitches), myotonia (delayed muscle relaxation), hypotonia (lack of resistance to passive movement), fixed muscle weakness (a static symptom), or premature muscle ...
As the muscle dies this will cause pain to radiate from the affected area into the compartmentalized tissue. A loss of range of motion from swelling will also be seen in the affected limb. Along with muscle strength weakness associated with the muscles involved from loss of filament interaction. [15] Compartment syndrome in muscle

Recurrent or episodic rhabdomyolysis is commonly due to intrinsic muscle enzyme deficiencies, which are usually inherited and often appear during childhood. [ 10 ] [ 13 ] Many structural muscle diseases feature episodes of rhabdomyolysis that are triggered by exercise, general anesthesia or any of the other causes of rhabdomyolysis listed above ...
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 .
