One day you might wake up with a painful blistering rash on one side of your body that looks like chicken pox. The odds are high that you have shingles, a skin condition caused by the herpes zoster virus. Shingles is a common condition—50% of all Americans will have had a breakout by the time they are 80. Your risk of shingles also increases as you get older—1 out of 3 people 60 years or older will get shingles.
