Idiopathic Inflammatory Myopathy – A rare autoimmune disorder that causes muscle inflammation and weakness. The condition primarily affects skeletal muscles, which are responsible for body movement. Muscle weakness typically develops gradually over weeks or months, mainly affecting the muscles closest to the trunk of the body, particularly those in the shoulders, hips, and thighs. Patients may experience difficulty with everyday tasks such as climbing stairs, getting up from chairs, or lifting objects. The condition can also be accompanied by skin changes, fatigue, and joint pain. Some people may develop swallowing difficulties as the muscles involved in swallowing can become affected.
