Overview
COVID-19 can lead to joint pain and, in some cases, reactive arthritis (joint inflammation that develops after an infection). It can also cause flare-ups in people with pre-existing inflammatory arthritis.
Symptoms
Joint pain, swelling, stiffness, especially in the knees, ankles, and feet. It can develop weeks after the initial infection.
Causes
The immune response to the virus can trigger inflammation in the joints. This can be a direct effect of the virus or an immune system overreaction.
Treatment
NSAIDs and pain relievers. In some cases, doctors may prescribe corticosteroids or other anti-inflammatory medications.
When to See a Doctor
If you have new joint pain after a COVID-19 infection, or if you have arthritis and your symptoms worsen, consult your rheumatologist.
