Polymyalgia Rheumatica is an inflammatory disorder that primarily affects older adults, typically those over 50 years old. It causes muscle pain and stiffness, especially in the shoulders, neck, and hips. Symptoms often develop quickly and can significantly impact daily activities. The exact cause of Polymyalgia Rheumatica is unknown, but it is believed to be related to an immune system response. Treatment usually involves corticosteroids, which help reduce inflammation and alleviate symptoms. Most patients respond well to treatment, experiencing relief within a few days to weeks.
