I have a friend with these symptoms!
A 25 year old woman presents to your primary care clinic with foot pain while running. Normally, she is asymptomatic, but when she runs, she feels numbness, tingling, aching, and burning of the distal forefoot. The pain radiates from the metatarsal heads to the third and fourth toes. The symptoms are worse while running on hard surfaces and while wearing tight high-heeled shoes. On physical exam, you note tenderness in the plantar foot over the point noted in the diagram above. Compressing that area creates a "click" and reproduces the patient's symptoms.
Challenge: What's the diagnosis?
