Pinched Nerve?

I was playing basketball yesterday and I twisted my ankle while playing. It hurt for a couple of minutes, but it didn't bother me the rest of the night. I assumed that it just hurt because of the impact and that it wasn't sprained; it didn't really feel like a spring either. Today though, when I'm just sitting down and stretching my foot, it feels a little weird at the top of my foot from where my leg ends to near my toes. It's just at the top of my foot and there's no pain in the surrounding areas or on the ankle. It's not the same pain as a sprain (soreness), but it's more of a sharp pain, but it feels like it's in a thin line at the top of my foot (parallel to the direction of my foot, not across).

Is this what a pinched nerve feels like? It seems like such a minor injury to see the doctor for and seems like it just requires a little rest so I'm wondering if anyone here knows.

Jam it back in, in the dark.
