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.
