What cause the tingling sensation on your right foot?

The tingling sensation is caused by the sudden rush of blood reaching a part which was pressed under something. If a part of your body is pressed under something too long, it will make a difficulty in for blood to reach that particular body part. When you remove your body part from getting pressed, there is a sudden rush as the blood flows into that body part. This causes the tingling sensation. I hop you have learnt something from this answer! :)
