Shingles (herpes zoster) results from a reactivation of the virus that also
causes chickenpox. With shingles, the first thing you may notice is a tingling
sensation or pain on one side of your body or face. Painful skin blisters then
erupt on only one side of your face or body along the distribution of nerves on
the skin. Typically, this occurs along your chest, abdomen, back, or face, but
it may also affect your neck, limbs, or lower back. The area can be very
painful, itchy, and tender. After one to two weeks, the blisters heal and form
scabs, although the pain often continues.
