from Mayoclinic

"The exact cause of polymyalgia rheumatica is unknown. Two factors appear to be involved in the development of this condition:

Genetics. Certain genes and gene variations might increase your susceptibility.

An environmental exposure. New cases of polymyalgia rheumatica tend to come in cycles, possibly developing seasonally. This suggests that an environmental trigger, such as a virus, might play a role. But no specific virus has been shown to cause polymyalgia rheumatica."
