Also known as: 異常感覚, パレステジア, 저림, 感觉异常
An abnormal sensation of the skin (tingling, pricking, chilling, burning, numbness) with no apparent physical cause. It happens when sustained pressure is placed on a nerve (from sitting with legs crossed for too long, or fallen asleep with an arm crooked under their head...) . The feeling quickly goes away once the pressure is relieved.
Also known in English as "[body part] falling asleep" or "Pins and Needles".
