That tingling feeling, like “pins and needles” in your hands or legs, is called paresthesia. It happens when constant pressure on a nerve cuts off blood flow, usually from staying put too long.
Most of the time, paresthesia is harmless and clears up fast once blood starts flowing again. Stretching or rubbing the spot can help you feel better quicker. But if it keeps coming back or turns chronic, it might mean there are hidden problems like nerve damage, stroke, or carpal tunnel syndrome.
