Foot Injury in a Weekend Warrior

A 46-year-old weekend warrior presents to an urgent care center 3 hours after injuring his right ankle and foot while playing basketball. He reports moderate to severe pain over the lateral side of the ankle and foot, which started after he jumped for a rebound and came down on the foot while it was in plantar flexion and inverted. However, he can walk. He reports no paresthesia or pain at the midfoot or proximal fibula, and there are no breaks in the skin of his right foot. He says that he did not experience any injury to his head or neck. He reports that he took over-the-counter ibuprofen but has not had adequate pain relief.
