What are the most common causes of muscle pain?
Most muscle pains are caused by a nonmuscular condition, such as vascular insufficiency, joint disease, or neuropathy.
The vast majority of myopathies are painless.
Myopathies that may be associated with pain include
- inflammatory myopathies,
- metabolic myopathies,
- mitochondrial myopathies,
- and some muscular dystrophies (limb-girdle, Becker muscular dystrophy [BMD]).
In general, in patients with a normal exam and a normal serum creatine kinase (CK) level, muscle pain is usually not myopathic in origin.
