Myositis and muscle disorders involve inflammation or damage to muscle tissue, resulting in weakness, pain, and reduced mobility. These conditions may develop due to autoimmune reactions, genetic factors, metabolic issues, infections, or medication side effects. Because muscle weakness often progresses slowly, early recognition and proper treatment are crucial to preserve muscle function, improve strength, and maintain an active, independent lifestyle.
Chronic or progressive muscle weakness, mainly affecting proximal muscles
Autoimmune forms include polymyositis, dermatomyositis, and inclusion body myositis
May be associated with skin rashes, fatigue, or difficulty swallowing and breathing
Diagnosis relies on blood tests, imaging, and sometimes muscle biopsy
Long-term management includes medications, physiotherapy, and regular follow-up
