Obdormition
Medical term describing numbness in a limb
From Wikipedia, the free encyclopedia
In medicine, obdormition (/ˌɒbdɔːrˈmɪʃən/; from Latin obdormire "to fall asleep") is temporary numbness in a limb, often caused by constant pressure on nerves or lack of movement.[1] This is colloquially referred to as the limb "going to sleep," and it is usually followed by paresthesia, colloquially called "pins and needles".
