Answer
: Hello Teresa. Doctors can distinguish shingles from chickenpox (or dermatitis or poison ivy) by the way the spots are distributed. Since shingles occurs in an area of the skin that is supplied by sensory fibers of a single nerve--called a dermatome--the rash usually appears in a well-defined band on one side of the body, typically the torso; or on one side of the face, around the nose and eyes. (Shingles' peculiar name derives from the Latin cingulum, which means girdle or belt.) If a diagnosis is in doubt, lab tests can confirm the presence of the virus.
