Why does the left side of my left foot hurt?

Foot pain: We love to help at health tap but can you repost with more details? It would make helping you much easier. The only advise i can give you now is to see a podiatrist.

Could be many reason: Could be anything, stress fracture, fracture, tendonitis, swelling, swollen muscle, infection, ankle sprain, over load from flat foot deformity, etc. Please clarify. Thanks.
