My dear friend, Emoş, asked me to investigate this disease and, or course, I couldn’t let her down.
Shingles is a viral infection that causes a painful rash. Shingles can occur anywhere on your body. It typically looks like a single strip of blisters that wraps around the left side or the right side of your torso.
Shingles is caused by the varicella-zoster virus – the same virus that causes chickenpox. After you’ve had chickenpox, the virus stays in your body for the rest of your life. Years later, the virus may reactivate as shingles.
Shingles isn’t life-threatening. But it can be very painful. Vaccines can help lower the risk of shingles. Early treatment may shorten a shingles infection and lessen the chance of complications. The most common complication is postherpetic neuralgia. This is a painful condition that causes shingles pain for a long time after the blisters have cleared.
Shingles symptoms usually affect only a small section on one side of the body. These symptoms may include:
- Pain, burning or tingling
- Sensitive to touch
- A red rash that begins a few days after the pain
- Fluid-filled blisters that break open and crust over
Some people also experience:
- Sensitivity to light
Pain is usually the first symptom of shingles. For some people, the pain can be intense. Depending on the location of the pain, it can sometimes be mistaken for problems with the heart, lungs, or kidneys. Some people experience shingles pain without ever developing the rash.
Most commonly, the shingles rash develops as a strip of blisters that wraps around either the left or right side of the torso. Sometimes the shingles rash occurs around one eye or on one side of the neck or face.
When to see a doctor
Contact your doctor as soon as possible if you suspect shingles, especially in the following situations:
- The pain and rash occur near an eye. If left untreated, this infection may lead to permanent eye damage.
- You’re 50 or older. Age increases the risk of complications.
- You or someone in your family has a weakened immune system. This may be due to cancer, medications, or chronic illness.
- The rash is widespread and painful.
Are you contagious?
A person with shingles can pass the varicella-zoster virus to anyone who isn’t immune to chickenpox. This usually occurs through direct contact with the open sores of the shingles rash. Once infected, though, the person will develop chickenpox rather than shingles.
Chickenpox can be dangerous for some people. Until your shingles scab over, you are contagious. Avoid physical contact with anyone who hasn’t had chickenpox or the chickenpox vaccine. That includes people with weakened immune systems, pregnant women, and newborns.
Complications from shingles can include:
- Postherpetic neuralgia. For some people, shingles pain continues long after the blisters have cleared. This condition is known as postherpetic neuralgia. It occurs when damaged nerve fibers send confused and exaggerated messages of pain from your skin to your brain.
- Vision loss. Shingles in or around an eye (ophthalmic shingles) can cause painful eye infections that may result in vision loss.
- Neurological problems. Shingles may cause inflammation of the brain (encephalitis), facial paralysis, or problems with hearing or balance.
- Skin infections. If shingles blisters aren’t properly treated, bacterial skin infections may develop.
A shingles vaccine may help prevent shingles. People who are eligible should get the shingles vaccine.
Shingrix is approved and recommended for people aged 50 and older, whether they’ve had shingles or not. People who’ve had the Zostavax vaccine in the past or don’t know whether they’ve had chickenpox may also receive the Shingrix vaccine.
Shingrix is also recommended for people who are 19 years of age and older, who have weakened immune systems due to disease or medication.
Shingrix is a nonliving vaccine made of a virus component. It’s given in two doses, with 2 to 6 months between doses. The most common side effects are redness, pain and swelling at the injection site. Some people also experience fatigue, headache, and other side effects.
The shingles vaccine doesn’t guarantee that you won’t get shingles. But this vaccine will likely reduce the course and severity of the disease. And it will lower your risk of postherpetic neuralgia. Studies suggest that Shingrix offers protection against shingles for more than five years.
Talk to your doctor about the vaccination options if you:
- Have had an allergic reaction to any component of the shingles vaccine
- Have a weakened immune system due to a condition or medication
- Have had a stem cell transplant
- Are pregnant or trying to become pregnant
The shingles vaccine is used only to prevent shingles. It’s not intended to treat people who currently have the disease.
There is no cure for shingles. Early treatment with prescription antiviral drugs may speed healing and lower the risk of complications. These drugs include:
- Acyclovir (Zovirax)
- Valacyclovir (Valtrex)
That’s it for now my friends; see you all the next time.
