myositis
Painful muscle inflammation
Myositis is inflammation of muscle tissue, causing weakness, pain, and swelling.
The condition may result from infection, injury, autoimmune disorders, or drug reactions.
In autoimmune forms like polymyositis and dermatomyositis, the immune system attacks healthy muscle: She was diagnosed with myositis after months of progressive muscle weakness.
