Shingles is a painful, blistering rash caused by the same virus as chickenpox (varicella zoster). Most people develop shingles in one part of the body. The blisters can last for several weeks.
The nerve pain from shingles can be severe and last for months. The pain can prevent you from doing daily activities such as walking, sleeping, or visiting with friends and family.
People with shingles may develop other problems, such as scarring in the area of the rash, skin infections, weakness, loss of hearing or vision, or paralysis (being unable to move part of your body).
Some people with shingles may need to be in the hospital if they are very unwell. In very rare cases, shingles can cause death.
