I smacked the top of my foot on a conrner of glass chasing my daughter?

i was chasing my daughter around tonite and smacked the top of my foot on a corner of glass. I cut it not bad tho and then i noticed my vein starting to pop out of my foot and swell up. it stings and burns when i put pressure on my foot. i feel on and off numbness and tingling. could it be just that i hit a nerve or should i be worried. i can feel throbbing in my foot as wel..
