Final answer:
Polymyalgia Rheumatica (PMR) is an autoimmune disease that causes pain and stiffness in the muscles, especially around the neck, shoulders, and hips. It is generally treated with corticosteroids and requires the supervision of a healthcare professional for proper management and dosage adjustment.
Step-by-step explanation:
Polymyalgia Rheumatica (PMR) is an autoimmune disease characterized by muscle pain and stiffness, particularly in the neck, shoulders, and hips. This condition is often associated with giant cell arteritis and primarily affects individuals over the age of 50. Although the precise cause of PMR is unknown, it is thought to involve abnormal immune system activity that causes inflammation of the affected tissues. Common symptoms of PMR include severe muscle aches and stiffness, especially in the morning or after inactivity, fever, fatigue, and weight loss.
Diagnosis is typically based on clinical evaluation, patient history, and tests like the erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP) levels, which indicate inflammation. PMR is treated with corticosteroids, which can significantly improve symptoms; however, it may take some time to find the optimal dose and tapering schedule. Unlike rheumatoid arthritis, PMR does not cause joint erosion or deformity, but it does require long-term medical management to control symptoms and improve patient quality of life.
