Myositis

When a muscle becomes inflamed without an obvious cause, it may be myositis: a group of conditions in which the muscles become inflamed and lose strength. It can affect one or several muscles and have various causes, from infections to immune system processes.

Common symptoms: muscle weakness, especially in the shoulders and hips, pain, fatigue, and difficulty with tasks such as climbing stairs or lifting objects.

Which specialist treats it? The rheumatologist is key when an immune cause is suspected, with support from the internist; the physical therapist takes part in functional recovery and the orthopedist when there are questions about the musculoskeletal system.

When to seek care? If muscle weakness is progressive or accompanied by persistent pain, the reasonable course is to seek an evaluation that identifies the cause and guides management with the appropriate professional.
