Polymyalgia rheumatica (PMR) is a common inflammatory illness that causes muscular pain and stiffness in the shoulders, neck, hips, and upper arm. The bulk of occurrences of PMR occur in people over 50, and women are more likely than males to be affected by it. PMR primarily affects older adults. In vulnerable individuals, infections, hormone fluctuations, and certain hereditary variables may contribute to the initiation or exacerbation of the inflammatory response.
