While checking history, the patient and her mother state that several weeks ago the patient was treated for an upper respiratory infection. The infection subsided after several days of taking antibiotics. However, several days later, the child complained of joint swelling and pain in her right elbow, which subsided, but then seemed to migrate to her left knee.
