Need help docs! my ankle and foot hurt after unknown gym activity. should i see a doctor?

Yes: Persistant pain particularly if it persists more that a day or two especially if associated with swelling and difficulty nutting weight on the foot/ankle should be evaluate by a doc. Exam, x-ray and possible MRI may be in order.

Foot and Ankle Pain: If you suspect injury, stay off your foot and see a Podiatrist. If no injury stop all level of activity and ice your foot and ankle for 3 days. If no improvement after 3 days you need to see a Podiatrist
