A runner increases her activity significantly after joining the college track team. A few weeks into her routine, she starts complaining of intermittent forefoot pain that occurs only with running, jumping, and dancing. The pain worsens until it occurs constantly with weight-bearing. On exam, you note point tenderness and swelling. When you hold the toe in line with the foot without angulation, pushing the toe into the metatarsal produces pain.
