Any idea on how to fix a pinched nerve?

I think this happened over 2 months ago or more. On my right foot, with the toe next to my pinky toe. The skin on the top part is some what numb like when you have a random body part to fall asleep. Then I try to point it and turn my foot in I get a sharp pain that I feel in that toe. I rather avoid seeing a doctor and wasting money there and want to see if I can some how fix this myself. I'm not even sure how I hurt it to begin with.
