What is "dermatomyositis"?

Dermatomyositis is a rare inflammatory condition that affects both the skin and muscles. It causes muscle weakness, pain, and fatigue, along with skin rashes and inflammation. These symptoms can make it challenging to perform daily activities like walking, climbing stairs, or lifting objects. The exact cause of dermatomyositis is not fully understood, but it is believed to involve an abnormal immune system response. Treatment typically involves medications to reduce inflammation and weaken the immune system's response. Physical therapy may also be recommended to help maintain muscle strength and function.
