Athens, GA Shingles
What is shingles?
Shingles is an infection of the nerves caused by the same virus that causes chickenpox. The virus is called varicella zoster. You cannot have shingles unless you have already had chickenpox (usually as a child).
Shingles is also called herpes zoster. This infection is most common in people over 50 years old.
How does it occur?
If you have had chickenpox, you are at risk for having shingles later on. After you recover from chickenpox, the chickenpox virus stays in your body. It moves to the roots of your nerve cells (near the spinal cord) and becomes inactive (dormant). The virus may become active again, but instead of causing chickenpox again, it causes shingles. The virus can become active again if your body’s immune system is weakened by:
- aging
- illness
- physical or emotional stress
- diseases such as AIDS or Hodgkin’s disease
- fatigue
- poor nutrition
- chemotherapy or radiation
- sunburn
- certain medicines, such as steroids
- Sometimes problems from herpes zoster happen for no known reason.
What are the symptoms?
The first sign of shingles is often burning, sharp pain, tingling, or numbness in your skin on one side of your body or face. The most common site is the back or upper abdomen. You may have severe itching or aching. You also may feel tired and ill with fever, chills, headache, and upset stomach or belly pain.
One to 14 days after you start feeling pain, you will notice a rash of small blisters on reddened skin. Within a few days after they appear, the blisters will turn yellow, then dry up and form scabs. Over the next 2 weeks the scabs drop off, and the skin continues to heal over the next several days to weeks.
Because shingles usually follows nerve paths, the blisters are usually found in a line, often extending from the back or side around to the belly. The blisters are almost always on just one side of the body. Shingles usually doesn’t cross the midline of the body. The rash also may appear on one side of your face or scalp. The painful rash may be in the area of your ear or eye. When shingles occurs on the head or scalp, symptoms can include headaches and weakness of one side of the face, which causes that side of the face to look droopy. The symptoms usually go away eventually, but it may take many months.
In some cases the pain can last for weeks, months, or years, long after the rash heals. This is called postherpetic neuralgia.
Is shingles contagious?
You cannot get shingles from someone else. However, if you have never had chickenpox, you may get chickenpox from close contact with someone who has shingles because the blisters contain chickenpox virus.
If you have shingles, make sure that anyone who has not had chickenpox or the chickenpox shot does not come into contact with your blisters until the blisters are completely dry. You are no longer contagious after the blisters dry up and form scabs.
How is it diagnosed?
Your Reddy Urgent Care healthcare provider will ask about your medical history and symptoms. Your provider will also examine your skin. The diagnosis is usually obvious from the rash. To confirm the diagnosis, you may have lab tests to look for the virus in fluid from a blister.
How is it treated?
It is best to start treatment as soon as possible after you notice the rash. See your Reddy Urgent Care healthcare provider to discuss treatment with antiviral medicine, such as acyclovir. This medicine is most effective if you start taking it within the first 3 days of the rash. Antiviral medicine may speed your recovery and lessen the chance that the pain will last for a long time.
Your provider may also recommend or prescribe:
- medicine for pain
- antibacterial salves or lotions to help prevent bacterial infection of the blisters.
Sometimes steroid medicine is prescribed, but it is not clear that it is helpful. In some cases it may make the infection worse. Ask your healthcare provider if steroids might be recommended in your case. Using a steroid for a long time can have serious side effects. Take steroid medicine exactly as your healthcare provider prescribes. Don’t take more or less of it than prescribed by your provider and don’t take it longer than prescribed. Don’t stop taking a steroid without your provider’s approval. You may have to lower your dosage slowly before stopping it.
How long will the effects last?
The blisters will heal in 1 to 3 weeks. For most people the pain then fades away in the first month or two after the blisters heal. When shingles occurs on the head or scalp, the symptoms usually go away eventually, but it may take many months.
If the virus damages a nerve, you may have pain, numbness, or tingling for months or even years after the rash is healed. This is called postherpetic neuralgia. This chronic condition is most likely to occur after a shingles outbreak if you are over 50. Taking antiviral medicine as soon as the shingles is diagnosed may help prevent this problem.
How can I take care of myself?
Take a pain-relief medicine such as acetaminophen. Take other medicine as prescribed by your healthcare provider.
- Put cool, moist washcloths on the rash.
- Rest in bed during the early stages if you have fever and other symptoms.
- Try not to let clothing or bed linens rub against the rash and irritate it.
Come to Reddy Urgent Care right away if:
- You develop worsening pain or fever.
- You develop a severe headache, stiff neck, hearing loss, or changes in your ability to think.
- The blisters show signs of bacterial infection, such as increasing pain or redness, or yellow drainage from the blister sites.
- The blisters are close to the eyes or you have pain in your eyes or trouble seeing.
- You have trouble walking.
- You have trouble breathing or a severe cough.
- You have a fever over 101.5? F (38.6? C.)
- You have a rash involving your eye or difficulty looking at bright light.
- The blisters look infected. Signs or symptoms of infection include:
- Your skin is getting redder or more painful.
- You have red streaks spreading from the blisters.
- The blister area gets very warm to the touch.
- Pus or other fluid starts leaking from the blisters.
- You have fever, chills, nausea, vomiting, or muscle aches.
How can I help prevent shingles?
- If you have never had chickenpox, you can get a shot to help prevent infection with the chickenpox virus.
- If you have had chickenpox, a vaccine, called Zostavax, is available for people 60 years of age and older. The vaccine can help prevent or lessen the symptoms of shingles. It cannot be used to treat shingles once you have it.
You can protect your immune system and lessen your chances of getting shingles by trying to keep stress under control, exercising regularly, and eating a healthy diet.
