If fractured, you will need to be immobilized with a splint, cast, or rigid walking boot depending on the location and severity of the injury. You may need foot surgery if the fracture is not stable or if it is displaced. Have you physician determine which course of treatment is best for you.

5th metatarsal: Pain, swelling, deformity at the site may be sprain but possibly fracture. Radiograph (xray) needed to r/o fracture. Fracture or severe sprain will require splinting. Fp/orthopedics/sports medicine/er docs can handle it & provide followup care.
