Shingles is very common. Fifty percent of all Americans will have had shingles by the time they are 80. While shingles occurs in people of all ages, it is most common in 60- to 80-year-olds.
What are the symptoms of shingles?
Shingles causes a painful, blistering rash. Sometimes the pain starts a few days before the rash appears.
The rash begins with reddish bumps. In a few days, these bumps turn into blisters. You might feel a stinging or burning pain. The rash may wrap around your back and chest, or it may be on one side of your face.
The blisters usually crust over and fall off after 7 to 10 days. You may see changes in the color of your skin when the scabs fall off. In bad cases of shingles, these color changes last forever.
Even though the rash gets better or goes away in a few weeks, the pain may last longer. In most people, the pain goes away in 1 to 3 months.
Shingles can also affect your eyes, causing swollen eyelids, redness and pain. Shingles of the eye can cause scars that affect your vision. It can also lead to glaucoma later in life. Glaucoma is an eye disease that can cause blindness. People who have shingles of the eye should see an eye doctor right away.
How is shingles treated?
Shingles is often treated with acyclovir (brand name: Zovirax), famciclovir (brand name: Famvir) or valacyclovir (brand name: Valtrex). Your doctor will decide which of these medicines might work for you. These medicines work better if you start taking them in the first 3 days after you get the rash.
Your doctor might also have you take a steroid medicine to reduce your pain and swelling.
Shingles of the eye is treated with antiviral medicines and steroids.
What can I do about the pain?
To help with the pain of shingles, your doctor might have you take an over-the-counter pain medicine like acetaminophen (one brand name: Tylenol) or ibuprofen (one brand name: Motrin). Aspirin is not recommended because using it might cause a liver problem called Reye's syndrome.
Putting a medicated lotion (two brand names: Benadryl, Caladryl) on the blisters might reduce the pain and itching. Putting cool compresses soaked in an astringent liquid (two brand names: Bluboro, Domeboro) on the blisters and sores might make them hurt or itch less.
If shingles causes severe pain, your doctor might have you take a prescription pain medicine.
What is postherpetic neuralgia?
"Postherpetic neuralgia" is the name used when the pain of shingles lasts for a long time after the rash is gone. About 1 in 5 people with shingles will get postherpetic neuralgia.
Like shingles, postherpetic neuralgia causes a stinging or burning pain. Your skin might become very sensitive to temperature changes or a light touch, such as from a bedsheet or moving air.
Most people with postherpetic neuralgia get better with time. Almost all of them are free of pain within 1 year. A few people have chronic pain (pain that doesn't go away).
How is postherpetic neuralgia treated?
Postherpetic neuralgia is often treated with over-the-counter pain medicines and capsaicin cream (two brand names: Capsin, Zostrix). If these medicines don't help enough, your doctor might try some other treatments, such as a patch that contains lidocaine (brand name: Lidoderm).
Some medicines that are used to treat depression and seizures can also help the nerve pain of postherpetic neuralgia. These medicines don't work very fast, though. It might be several weeks before they help your pain.
Can I give shingles to others?
No one can catch shingles from you, but they can catch chickenpox if they haven't already had chickenpox or had the chickenpox vaccine. The chickenpox virus lives in the blisters from shingles, and the virus can be spread until the blisters are completely healed. If you have shingles, you should stay away from babies younger than 12 months and pregnant women.
