  • Acquired, familial, and congenital disorders of skeletal muscle and smooth muscle.
  • Impairment of health or a condition of abnormal functioning of the muscle.

    • injury or overuse, such as sprains or strains, cramps or tendinitis
    • genetics, such as muscular dystrophy
    • some cancers
    • inflammation, such as myositis
    • diseases of nerves that affect muscles
    • infections
    • certain medicines
