M60.9: Myositis, unspecified
Myositis refers to an inflammatory condition that directly affects the muscles in the body. This condition is characterized by swelling and weakness of the muscles, leading to varying degrees of localized pain and muscle stiffness. Some possible signs includes difficulty swallowing or breathing, muscle pain, fatigue, and unexpected weight loss. While the exact cause of myositis is unknown, it can be triggered by various elements like certain viral infections or a malfunctioning immune system that mistakenly attacks the body's own tissues. Myositis can either develop gradually or present suddenly with severe symptoms. The severity and progression of myositis may differ from one individual to another. In severe instances, the disease can cause considerable debilitation and interfere with basic everyday activities like walking, carrying objects, or even consuming food.
