I know it happens because the blood can't flow as well - but what actually causes the pins-and-needles effect?

I've always heard it's your body's way of telling you that there is, indeed, a lack of blood flow. Your nerve endings are "looking" for blood flow. If there is low blood flow they will tingle to alarm you that you need to do something to get blood flowing again.

The pins and needles feeling you are experiencing is the blood circulation has been interrupted, by crossing your legs, of having one of your limbs in an awkward position, so not enough blood is getting to your extremity. It is your body's way of letting your know something is not right, so once you strraighten your limb, the blood will start flowing properly again.

it happens because not enough oxygen is getting to that part of the body, but i don't know why it hurts so much after, maybe its because while the blood bringing the oxygen in is rushing so fast.
