The duration of acute arthritis can range from a few weeks or months to years or even a lifetime. It can also be persistent. IA types include autoimmune and autoinflammatory illnesses. This suggests that the immune system, which is meant to fight off viruses and pathogens, becomes confused and attacks the body's cells and tissues. The doctor can suggest blood testing for C-reactive protein and erythrocyte sedimentation rate. These blood tests evaluate inflammatory markers or markers of inflammation.
