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 in 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. The blisters are contagious with skin to skin contact. After one to two weeks, the blisters heal and form scabs, although the pain can continue. Early treatment can lessen the duration of disease and may alleviate post herpetic pain. Read more about shingles.
