Herpes zoster, commonly known as shingles, is a viral infection that causes a painful, blistering rash. It is caused by the reactivation of the varicella-zoster virus, the same virus that causes chickenpox.
After a person has had chickenpox, the virus can remain dormant in the nervous system for years or even decades. If the virus reactivates, it can cause shingles. The risk of reactivation increases with age and with weakened immune systems, such as in people with HIV or those undergoing cancer treatment.
The first symptom of shingles is often a burning or tingling sensation in one area of the body, usually on one side of the torso or face. This is followed by the appearance of a painful, blistering rash, which can last several weeks. Other symptoms may include fever, headache, and fatigue.
Treatment for shingles includes antiviral medications, such as acyclovir or valacyclovir, which can reduce the severity and duration of the illness if started early. Pain medications may also be prescribed to manage the discomfort. Vaccines are available to prevent shingles, and are recommended for adults over the age of 50.
Complications from shingles can include postherpetic neuralgia, a condition in which nerve pain persists for months or even years after the rash has healed. Other rare but serious complications can include vision loss or inflammation of the brain. It is important to seek medical attention promptly if you suspect you may have shingles, especially if you are at risk for complications.
