Immune System Issues
Many health issues with the immune system can be a cause of polymyalgia rheumatica. Autoimmune disorders can make this part turn against your own body cells, thus triggering inflammation. In most cases, these problems tend to be a combination of environmental triggers and genetic predisposition. Another risk factor comes from the immune system itself. Blood tests suggest that cells from this part can penetrate the synovial membrane of tendons and joints, which results in inflammation. [10]
