Recognizing Myopathy in Patients with Muscle Weakness or Pain.

Muscle weakness and pain can be seen in orthopedic, rheumatologic, cardiac, and musculoskeletal conditions in addition to neurologic disorders. Myopathy, which describes a heterogenous group of hereditary and acquired disorders that affect muscle channels, structure, and metabolism, is one possible cause. This review focuses on essential information to support primary care providers as they assess patients with muscle weakness and pain for myopathy. As with most neurologic disorders, a thorough clinical history and physical examination are essential first steps. These findings will then guide diagnostic testing and facilitate appropriate management or referral for further neuromuscular care.
