Ask a question


Paresthesia is the scientific term given to the sensation of pins and needles, numbness, or other tingling feelings that can be experienced in different parts of the body, in particular in the limbs and their extremities (arms, hands, legs, feet). Paresthesia can at times be accompanied by a temporary loss of feeling. This condition is neurological in origin, caused by damage to a part of a nerve, secondary to pressure on a nerve somewhere along its pathway or to a neurological disease. Paresthesia also refers to problems of perception of information by touch, which can involve heat, cold, pain, and so on.
