Why do your limbs tingle after they fall asleep?

My foot just fell asleep in class and I was wondering where the super uncomfortable tingling comes from.

It come from your nerves "waking up." You can have a limb in a position that cut or reduced the sensory signals that are sent to the brain. Then when the connection is restored, the tingling is your brain sensing everything (like pretty much the weight of your own skin) before it remembers to filtering it out.
