Polymyalgia rheumatica (PMR) is a disorder of the muscles and joints that causes pain and stiffness in the arms, neck, shoulders, and buttocks. Treatment for polymyalgia rheumatica aims to reduce inflammation with aspirin, ibuprofen and low doses of cortisone medications. Giant cell arteritis, inflammation of blood vessel walls, affects 10-15 percent of polymyalgia rheumatica patients. Symptoms of giant cell arteritis include fatigue, weight loss, low-grade fever, jaw pain when chewing, scalp tenderness, and headaches. High doses of cortisone medications are used to treat giant cell arteritis.
Dr. Shiel received a Bachelor of Science degree with honors from the University of Notre Dame. There he was involved in research in radiation biology and received the Huisking Scholarship. After graduating from St. Louis University School of Medicine, he completed his Internal Medicine residency and Rheumatology fellowship at the University of California, Irvine. He is board-certified in Internal Medicine and Rheumatology.
Catherine Burt Driver, MD, is board certified in internal medicine and rheumatology by the American Board of Internal Medicine. Dr. Driver is a member of the American College of Rheumatology. She currently is in active practice in the field of rheumatology in Mission Viejo, Calif., where she is a partner in Mission Internal Medical Group.
Giant cell arteritis is detected by a biopsy of an artery.
Giant cell arteritis is treated with high-dose cortisone medications.
What is polymyalgia rheumatica?
Polymyalgia rheumatica is a disorder of the muscles and joints characterized by muscle pain and stiffness, affecting both sides of the body, and involving the shoulders, arms, neck, and buttock areas. Patients with polymyalgia rheumatica are typically over 50 years
of age. Polymyalgia rheumatica is abbreviated PMR.
Because both polymyalgia rheumatica and giant cell arteritis sometimes occur in the same patient, both diseases are reviewed here.
What causes polymyalgia rheumatica?
The cause of polymyalgia rheumatica is not known. Recent
indicated that genetic (inherited) factors play a role in who
afflicted with the illness. Theories have included viral
the immune system in genetically susceptible individuals. Rarely, polymyalgia rheumatica is associated with a cancer. In this setting, the cancer may be initiating an inflammatory immune response to cause the polymyalgia rheumatica symptoms.
What are symptoms and signs of polymyalgia rheumatica?
The onset of the illness can be sudden. A patient may have a
history until awakening one morning with stiffness and pain of
joints throughout the body. These pains can lead to a sensation of weakness and loss of function. Sometimes there is also muscle tenderness. These symptoms persist and are often
accompanied by an intense sensation of fatigue. Some patients
gradual loss of appetite, weight, and energy. Depression can
The diagnosis of polymyalgia rheumatica is suggested by the history and physical examination.
The doctor frequently notes muscle tenderness and that the
motion of the
shoulders is limited by pain. The joints are usually not

Blood testing for inflammation is generally abnormal, as
indicated by a
significant elevation in the erythrocyte sedimentation rate
(sed rate or ESR) and/or C-reactive protein. There
are no specific tests, however, for polymyalgia rheumatica and
normal. The diagnosis is based on the characteristic history of
muscle and joint pain and stiffness associated with
elevated blood tests for inflammation, such as the ESR. It is also not unusual for patients to have slight elevations of
liver blood tests.
Although a fever could be considered any body temperature above the normal 98.6 F (37 C), medically, a person is not considered to have a significant fever until the temperature is above 100.4 F (38.0 C)."...
