Shingles is caused by the same virus that causes chickenpox. Once you have had chickenpox, the virus stays in your body and can resurface as Shingles-a painful, blistering rash. The Shingles rash usually last up to 30 days, and for most the pain lessens as the rash heals. But some people who develop Shingles experience long-term pain that can last for months, even years.
And your chances of getting Shingles increase substantially after age 60.
