I almost fell but i landed on my foot in the wrong way. i'm in extreme pain on the top side of my left foot. what have i damaged possibly?

Ankle Sprain: Likely you have an ankle sprain if you can bear weight and no bony deformities. This is usually a torn Anterior Talofibular ligament and should get better with time and NSAID therapy. If does not improve, or if worsens, you need to be evaluated to r/o fracture or worse injury.

See details: There are several possibilities including fracture and soft tissue injuries. Have the foot evaluated and xrayed.
