Polymyalgia rheumatica (sometimes referred to as PMR) is a common cause of widespread aching and stiffness that affects adults over the age of 50, especially Caucasians. Because polymyalgia rheumatica does not often cause swollen joints, it may be hard to recognize. It may occur with another health problem, giant cell arteritis.
The average age when symptoms start is 70, so people who have PMR may be in their 80s or even older. The disease affects women somewhat more often than men. It is more frequent in whites than nonwhites, but all races can get PMR.
