10-year-old female with no medical history presents to the ER with 6 days of daily fevers. Highest temperature of 104 orally and controlled with Tylenol and Motrin. Family also mentions right leg pain. Family noticed she was limping about 1 week ago and seemed to favor the right leg. It is difficult for the patient to describe the pain – she says it’s sharp sometimes at the right knee when she straightens the leg or puts weight on it. That sensation has subsequently disappeared as of 2 days ago. Today she denies leg pain and is no longer limping.
