Shingles, also known as zoster or herpes zoster, is a painful skin rash caused by the varicella zoster virus, the same virus that causes chickenpox. Nearly 1 out of every 3 people in the United States will develop shingles. Anyone who has recovered from chickenpox may develop shingles; even children can get shingles. However, the risk of getting the disease increases as a person gets older. About half of all cases occur among men and women who are 60 years old or older.
What causes shingles?
Shingles occurs when the virus that causes chickenpox starts up again in your body. After you get better from chickenpox, the virus “sleeps” (is dormant) in your nerve roots. In some people, it stays dormant forever. In others, the virus “wakes up” when disease, stress, or aging weakens the immune system. Some medicines may trigger the virus to wake up and cause a shingles rash. It is not clear why this happens. But after the virus becomes active again, it can only cause shingles, not chickenpox.
You can’t catch shingles from someone else who has shingles. But there is a small chance that a person with a shingles rash can spread the virus to another person who hasn’t had chickenpox and who hasn’t gotten the chickenpox vaccine.
How is shingles treated?
Shingles is treated with medicines. These medicines include antiviral medicines and medicines for pain.
Starting antiviral medicine right away can help your rash heal faster and be less painful. So if you think you may have shingles, see your doctor right away.
Good home care also can help you feel better faster. Take care of any skin sores, and keep them clean. Take your medicines as directed. If you are bothered by pain, tell your doctor. He or she may write a prescription for pain medicine or suggest an over-the-counter pain medicine.
What are the symptoms?
Shingles symptoms happen in stages. At first you may have a headache or be sensitive to light. You may also feel like you have the flu but not have a fever.
Later, you may feel itching, tingling, or pain in a certain area. That’s where a band, strip, or small area of rash may occur a few days later. The rash turns into clusters of blisters. The blisters fill with fluid and then crust over. It takes 2 to 4 weeks for the blisters to heal, and they may leave scars. Some people only get a mild rash, and some do not get a rash at all.
It’s possible that you could also feel dizzy or weak, or you could have long-term pain or a rash on your face, changes in your vision, changes in how well you can think, or a rash that spreads. If you have any of these problems from shingles, call your doctor right away.
Who gets shingles?
Anyone who has had chickenpox can get shingles. You have a greater chance of getting shingles if you are older than 50 or if you have a weak immune system.
There is a shingles vaccine for people who are 50 years and older. This lowers your chances of getting shingles and prevents long-term pain that can occur after shingles. And if you do get shingles, having the vaccine makes it more likely that you will have less pain and your rash will clear up more quickly.
