Patient Presentation:
A previously healthy 11-year-old boy presented to the sports medicine clinic with 1 month of right leg and foot pain.
History:
The patient presented initially to his pediatrician who thought the pain was due to a hamstring strain or growing pains, but symptoms were followed by 2 weeks of right foot and ankle pain with weakness. The pain was so severe that it woke him up at night despite taking tylenol and motrin every 3 hours. He endorsed at least 2 episodes of tripping and falling due to his "foot giving out." According to his parents, he had been "walking funny." As a result, he was evaluated at an outside hospital emergency room a week ago with normal x-rays of the hip, foot and ankle. He was discharged and referred to sports medicine. Denied injury, trauma, fever, recent illness, diarrhea, vomiting, urinary or fecal incontinence. There was no recent travel except for a road trip to South Dakota and Wyoming a few months ago, where he went hiking, kayaking, and paddleboarding. He denied any bug bites or ticks. He reported decreased oral intake for the past week but no weight loss.
