What is causing transient migratory bouts of arthritis in this young man and how should he be managed?
Anton, aged 38 years, has had an apparent migratory polyarthritis over the past few months. He has had joints affected sequentially with severe pain, heat, swelling and restricted mobility. Symptoms develop in the affected area, last several days to a couple of weeks and then resolve completely, only to be replaced by similar symptoms in a different joint. The sites affected have been his shoulder, wrists, knuckles and interphalangeal joints and, most recently, a knee.
