Shingles is a viral infection caused by the varicella-zoster virus (chickenpox virus). In people who have had chickenpox, the virus can lie dormant in nerve tissue for years and then reactivate as shingles. Shingles usually appears as a painful rash and blisters on the skin, usually in one area of the body. The pain may begin a few days before or after the rash, and in some cases, the pain may occur without the rash. Shingles is most common in older people and people with weakened immune systems, but it can occur at any age.
Symptoms of Shingles
Unilateral and strip-shaped rash
Red blisters on the skin
Pain, burning, tingling or tenderness
Flu-like symptoms such as fever, headache, and fatigue
Shingles Treatment Methods
Antiviral drugs: Antiviral drugs used to treat shingles can stop the virus from multiplying and reduce the severity and duration of symptoms. Treatment is most effective when started within 72 hours of the onset of symptoms. The most commonly used antiviral drugs are acyclovir, valacyclovir, and famciclovir.
Pain Management: Over-the-counter pain relievers, prescription pain medications, anticonvulsants, and antidepressants can be used to manage shingles pain.
Topical Solutions: Calamine lotion and cold compresses can be used to relieve skin discomfort.
Corticosteroids: In severe cases, oral corticosteroids may be prescribed to reduce inflammation and manage pain. However, these medications may not be appropriate for every patient.
Frequently Asked Questions
Is shingles contagious?
Shingles itself is not contagious, but the virus in shingles blisters can spread to people who have not had chickenpox or have not had the chickenpox vaccine and cause them to develop chickenpox.
What causes shingles?
Shingles occurs when the varicella-zoster virus is reactivated in people who have had chickenpox before. A weakened immune system, stress, advanced age, and certain diseases can trigger the virus to reactivate.
How long does shingles pain last?
Shingles pain can continue even after the rash has healed. This condition is called postherpetic neuralgia and can last for weeks, months, or even years in some people.
Can shingles be prevented?
The shingles vaccine can reduce the risk of shingles and the likelihood of postherpetic neuralgia. The shingles vaccine, recommended for adults age 50 and older, is effective in preventing shingles and its complications.
