muscle inflammation

Muscle inflammation, known as myositis, is when your muscle tissues become swollen and irritated due to injury, overuse, or immune system activity. This condition can cause pain, swelling, weakness, and stiffness in the affected muscles. The inflammation occurs because the body sends extra blood and immune cells to repair damage or fight perceived threats, which can sometimes lead to tissue swelling. Causes vary from physical strain to autoimmune diseases. Treatment typically involves rest, anti-inflammatory medications, and physical therapy to reduce symptoms and promote healing.
