Paresthesias are abnormal sensations experienced in the absence of specific stimuli.1(p1234),2 These sensations are usually described as burning, tingling or numb feelings, although they may be described as feelings of cold, warmth, prickling, pins and needles, skin crawling or itching.2 The most common locations of paresthesias are the hands, arms, legs and feet, although paresthesias can be present anywhere on the body. Paresthesias are contrasted with dysesthesias, which are abnormal interpretations of appropriate stimuli.1(p515),2 Paresthesias are common presenting complaints, and diagnosis is usually assisted by knowing the specific clinical presentations associated with various paresthetic syndromes. |
