Foot Sprain: It is quite possible that you sprained it without knowing. To exclude any fracture you should have x-ray. Rest and ice will help your pain along with analgesics.

See a podiatrist: No way to tell if sprain or something else without an exam.

It is possible: Sprains are common injuries resulting from playing basketball. If you continue to have pain and swelling have it evaluated by a professional.

Stress fractures: See a podiatrist or orthopedist to rule out stress fractures if your feet with referred pain to your ankle.
