Myositis is a rare autoimmune disease that affects the muscles and causes inflammation, weakness, and fatigue. There are several different types of myositis, each with their own distinct symptoms and patterns of muscle involvement. The most common types include dermatomyositis, polymyositis, and inclusion body myositis.
Symptoms of myositis typically develop slowly over time and can include difficulty climbing stairs, rising from a chair, or lifting objects. Patients may also experience muscle pain, joint pain, and a rash on the face or chest in the case of dermatomyositis.
Although there is no cure for myositis, treatment can help manage symptoms and slow the progression of the disease. Treatment typically involves a combination of medication and physical therapy to strengthen muscles and improve function. Early diagnosis and treatment is important in order to prevent muscle damage and improve outcomes for patients. Ongoing management is also important to prevent complications and maintain quality of life.
