Initially, the pain was intermittent but it is now constant and she describes it as 8 out of 10 in intensity. She has not had any trauma to the foot or any previous problems with her joints. The pain has not allowed her to continue training for an upcoming marathon. Her only medication is an oral contraceptive. She is a model and has to regularly wear stilettos for fashion shows. She appears healthy. Vital signs are within normal limits. Examination shows swelling of the right forefoot. There is tenderness to palpation over the fifth metatarsal shaft. Pushing the fifth toe inwards produces pain. The remainder of the examination shows no abnormalities. Which of the following is the most likely diagnosis?? A: Mortons neuroma, B: Acute osteomyelitis, C: Stress fracture, D: Plantar fasciitis, E: Freiberg disease,  <response>: This is a clinical case scenario describing a 26-year-old woman with increasing pain and swelling in her right foot over the past 2 weeks. The key findings in the history are increasing pain after initially being intermittent, no prior trauma, and the pain preventing her from training for a marathon. On physical exam, there is swelling and tenderness localized to the fifth metatarsal shaft, and pain with pushing the fifth toe inward. Based on the history of overuse without trauma in a marathon trainee, the focal exam findings involving the fifth metatarsal, and the patients occupation requiring her to wear stilettos, the most likely diagnosis is a stress fracture of the fifth metatarsal. Mortons neuroma is unlikely as this presents with forefoot pain between the metatarsals. Osteomyelitis would present with systemic symptoms. Plantar fasciitis typically causes heel pain. Freiberg disease may cause pain in the metatarsal head but not shaft.C: Stress fracture
