Palindromic rheumatism is a rare form of arthritis that involves sudden bouts of joint pain and swelling, sometimes without warning, states Healthline. These episodes usually occur in the hands and feet and can last anywhere from a few hours to several days.
While related to rheumatoid arthritis (RA), palindromic rheumatism (PR) can be sudden and infrequent. There is no conclusive cause for PR, though many researchers believe it is strongly connected to RA. Since PR is so rare, it is typically diagnosed after other more common causes are eliminated. It is typically treated with the same medications used for malaria. It is also common for doctors to prescribe nonsteroidal anti-inflammatory drugs (NSAIDS) to help further reduce swelling and inflammation, notes Healthline.
