Chickenpox is caused by the varicella-zoster virus, which can remain dormant in your system long after the initial illness. Should the virus become reactivated, an infection called shingles (herpes zoster) will occur.
Like chickenpox, shingles causes rash. However, people also experience intense bouts of nerve pain that can last for months or even years after the infection has resolved. A shingles vaccine can help you avoid these effects, and doctors can use medication to manage symptoms in those who are unvaccinated.
Shingles often occurs in people over the age of 50, so older adults who have experienced the varicella-zoster virus in the past should consider getting vaccinated. The shingles vaccine can prevent painful symptoms and possible complications, such as vision loss and facial paralysis, from occurring.
Most people are eligible for the vaccine, including those who have had shingles before. However, people with active infections must wait for it to clear before receiving the vaccine. A medical professional can assess your health and offer a recommendation.
There is no cure for shingles, but antiviral medications can decrease the intensity of symptoms when taken within three days of onset. Corticosteroids and non-prescription pain relievers can also help manage symptoms.
Regardless of the severity of symptoms, schedule an appointment with a doctor if you suspect a shingles infection. You should also seek emergency medical attention for the following:
These effects could indicate serious health problems, so they must be addressed immediately.
