Polymyalgia (poly = many; myalgia = aching muscles) rheumatica (PMR) is an inflammatory rheumatic condition. It affects around 4 per 1000 people over the age of 50. Symptoms can start abruptly, or can come on over a week or two.

Both men and women are equally affected. Although it is common in Caucasians and rare in Asians and Afro-Caribbeans.

PMR causes sudden/abrupt pain and morning stiffness, mainly in and around the shoulders and thighs (it may also affect the neck and torso). Often, patients cannot get out of bed without help and notice difficulty climbing stairs.

Prolonged rest or inactivity may increase the stiffness and activities such as driving become more difficult.

Other common complaints include feeling generally unwell and tired. Occasionally, a slight fever accompanies the condition. Some patients notice a loss of appetite and weight.

In the most severe form of PMR, painful inflammation occurs in the arteries in the head, particularly around the temple area: this is called temporal arteritis.

Fortunately, no organ systems are usually affected, eg no liver, kidney or lung damage is done in typical PMR.
