Shingles causes a painful, blistering rash for most people. It is a reactivation of the same virus that causes chicken pox. If you've had chicken pox, the virus can return as shingles and affect the nerves.
See a doctor immediately if you think you may have shingles. Starting a prescription within 2 to 3 days of developing the rash can substantially reduce pain and shorten the duration. See the doctor even if it's been longer to lower the risk of other serious health issues
The shingles vaccine, available at pharmacies, has been proven as the most effective method to reduce the risk.
