Paresthesia: Paresthesia is an abnormal condition in which you feel a sensation of burning, numbness, tingling, itching or prickling. Paresthesia can also be described as a pins-and-needles or skin-crawling sensation. Paresthesia most often occurs in the extremities, such as the hands, feet, fingers, and toes, but it can occur in other parts of the body.
