M12.3: Palindromic rheumatism

Palindromic rheumatism is a rare type of arthritis that causes episodes or "attacks" of joint discomfort and swelling. The term 'palindromic' describes the way the disease comes and goes, similar to the mirrored sequence of a palindrome. One unique characteristic of this condition is that the symptoms often disappear completely between attacks, leaving no long-term damage. Affected joints, which can include the knees, hands, wrists, and feet, become tender, red, and swollen, but then return to their normal state once the flare-up is over. These episodes can last from a few hours to several days. The exact cause of palindromic rheumatism is unknown, but it may be related to problems with the immune system, or could possibly be linked to infections or allergies. Severe tiredness and fever can accompany flare-ups, but there are no certain signs or symptoms to predict an attack.
