WHAT YOU NEED TO KNOW:
What is shingles?
Shingles is a painful rash. Shingles is caused by the same virus that causes chickenpox (varicella-zoster). After you get chickenpox, the virus stays in your body for several years without causing any symptoms. Shingles occurs when the virus becomes active again. The active virus travels along a nerve to your skin and causes a rash.
What are the signs and symptoms of shingles?
Shingles often starts with pain in the back, chest, neck, or face. A rash then develops in the same area. The rash is usually found on only one side of the body. The rash may feel itchy or painful. It starts as red dots that become blisters filled with fluid. The blisters usually grow bigger, become filled with pus, and then crust over after a few days. You may also have any of the following:
- Fatigue and muscle weakness
- Pain when your skin is lightly touched
- Eye pain when exposed to light
What increases my risk for shingles?
- Age older than 50
- Exposure to the virus while your mother was pregnant with you
- A medical condition such as cancer, AIDS, or Hodgkin disease
- Treatment for cancer that decreases your immune system
- Stressful life events that weaken your immune system
- An organ or stem cell transplant
How is shingles diagnosed?
Your healthcare provider will ask about your symptoms. Tell your provider if you have had chickenpox. Tell him or her if you have recently been around anyone who has chickenpox or shingles. The appearance of your rash will usually be enough for your healthcare provider to know you have shingles. He or she may also send skin scrapings or fluid from your blisters for tests.
How is shingles treated?
- Antiviral medicine helps decrease symptoms and healing time. It may also decrease your risk for nerve pain. You will need to start taking this medicine within 3 days of the start of symptoms to prevent nerve pain.
- Pain medicine may be prescribed or suggested by your healthcare provider. You may need NSAIDs, acetaminophen, or opioid medicine depending on how much pain you are in.
- Topical anesthetics are used to numb the skin and decrease pain. They can be a cream, gel, spray, or patch.
- Anticonvulsants decrease nerve pain and may help you sleep at night.
- Antidepressants may be used to decrease nerve pain.
- Epidural medicine is put into your spine to block pain. This medicine treats severe pain that does not get better with other pain medicines. Epidural medicine includes numbing medicine and steroids.
Can I infect others?
The virus can be passed to a person who has never had chickenpox. This person may get chickenpox, but not shingles. You may pass the virus to others as long as you have a rash. The virus is spread by direct contact with the fluid from the blisters. Usually, you cannot spread the virus once the blisters dry up.
How can I care for myself?
Keep your rash clean and dry. Cover your rash with a bandage or clothing. Do not use bandages with adhesive. These may irritate your skin and make your rash last longer.
How can I prevent the spread of germs?
- Wash your hands often. Wash your hands several times each day. Wash after you use the bathroom, change a child's diaper, and before you prepare or eat food. Use soap and water every time. Rub your soapy hands together, lacing your fingers. Wash the front and back of your hands, and in between your fingers. Use the fingers of one hand to scrub under the fingernails of the other hand. Wash for at least 20 seconds. Rinse with warm, running water for several seconds. Then dry your hands with a clean towel or paper towel. Use hand sanitizer that contains alcohol if soap and water are not available. Do not touch your eyes, nose, or mouth without washing your hands first.
- Cover a sneeze or cough. Use a tissue that covers your mouth and nose. Throw the tissue away in a trash can right away. Use the bend of your arm if a tissue is not available. Wash your hands well with soap and water or use a hand sanitizer.
- Stay away from others while you are sick. Avoid crowds as much as possible.
- Ask about vaccines you may need. Talk to your healthcare provider about your vaccine history. He or she will tell you which vaccines you need, and when to get them.
What can I do to help prevent shingles or a shingles outbreak?
A vaccine may be given to help prevent shingles. You can get the vaccine even if you already had shingles. The vaccine can help prevent a future outbreak. If you do get shingles again, the vaccine can keep it from becoming severe. The vaccine comes in 2 forms. Your healthcare provider will tell you which form is right for you. The decision is based on your age and any medical conditions you have. A 2-dose vaccine is usually given to adults 50 years or older. A 1-dose vaccine may be given to adults 60 years or older.
