Myositis refers to a group of conditions characterized by inflammation and weakness of the muscles. It can occur due to autoimmune reactions, infections, or certain medications. Patients typically present with progressive muscle weakness, fatigue, difficulty in climbing stairs, lifting objects, or even swallowing in severe cases. Other muscle disorders may include genetic conditions like muscular dystrophy or metabolic muscle diseases affecting energy production. Diagnosis involves blood investigations (muscle enzymes), electromyography, and sometimes muscle biopsy. Treatment depends on the underlying cause and may include immunosuppressive therapy, physiotherapy, and lifestyle modifications. Early intervention is essential to prevent muscle damage, improve mobility, and enhance overall quality of life.
