Also Known As: Paresthesia, numbness, pins and needles
Paresthesia is a sensation of tingling, tickling, prickling, pricking, or burning of a person's skin with no apparent long-term physical effect. The manifestation of a paresthesia may be transient or chronic.
The most familiar kind of paresthesia is the sensation known as "pins and needles" or of a limb "falling asleep". A less well-known but still fairly common paresthesia is formication.
