Polymyositis is a long-term, or chronic, inflammatory muscle disease that causes progressive weakness in the skeletal muscles. These are the muscles involved in movement, especially those closest to the trunk like the shoulders, hips, and thighs. It can also affect the neck and upper arms, making daily activities more difficult. Polymyositis occurs when the immune system mistakenly attacks healthy muscle tissue, making it an autoimmune condition. It differs from conditions like muscular dystrophy, which are inherited. In polymyositis, inflammation causes muscle fibers to break down over time. This leads to weakness rather than joint pain and can eventually impact swallowing or breathing if left untreated.
The inflammation in polymyositis may also involve the lungs or heart. Early diagnosis and proper treatment with medication and physical therapy can improve muscle strength and prevent serious complications. Without care, the condition can cause long-term muscle damage and disability.
Polymyositis is a chronic condition that causes inflammation of the muscles, leading to progressive weakness, fatigue, and difficulty performing everyday activities if not properly managed.
Diagnosing polymyositis early is important, but its initial symptoms can mimic other muscle disorders, making it difficult to identify.
Although polymyositis cannot be cured, early intervention with medications and physical therapy can help manage symptoms and prevent long-term muscle damage.
Physical therapy and, in rare cases, surgery can help restore strength, enhance mobility, and address complications when medications alone are insufficient.
