How many gashes make a gimp?

3. Last night I took a cm-wide layer of skin off my ankle from a carpet burn while "breakdancing." Today I went surfing and got nickeed on the foot from a rock. Then my board (new and under-waxed) slipped out under me, and the fin cut me under my knee. This is all on the right leg.

I wouldn't have guessed it, but the carpet burn is giving me the most pain. The fin cut, however, is causing the limp - the cut itself isn't that deep but I think it also bruised or something.
