What is it called when the foot goes to sleep?

The term for when the foot "goes to sleep" is paresthesia. It refers to a temporary sensation of numbness, tingling, or prickling in a body part, often caused by pressure or nerve irritation. In the case of the foot, it usually occurs when the peroneal nerve, which runs along the outside of the lower leg and controls sensation and movement in the foot and toes, is compressed or irritated. This can happen due to prolonged sitting or kneeling in an awkward position, or due to certain medical conditions such as diabetes or vitamin B12 deficiency.
