Shingles facts

  • Shingles is caused by the same virus that causes chickenpox and can be spread to people who have not had chickenpox.
  • Shingles, also known as herpes zoster, is not related to the sexually transmitted herpes virus disease called herpes genitalis, or the oral herpes virus, herpes simplex.
  • Shingles may cause pain that can continue after the rash disappears.
  • Postherpetic neuralgia is the most common complication of shingles.
  • Steroids and antiviral drugs can help prevent long-term pain after shingles if they are started within the first two days of the appearance of the rash.
  • The Zostavax vaccine is available for people over 60 years of age to reduce the incidence and severity of shingles.

What is shingles? What causes shingles?

Shingles is a skin rash caused by a nerve and skin inflammation from the same virus that previously caused chickenpox. This virus is called the varicella zoster virus (VZV) and belongs to the herpes family of viruses. After an individual has chickenpox, this virus lives dormant in the nervous system and is never fully cleared from the body. Under certain circumstances, such as emotional stress, immune deficiency (from AIDS or chemotherapy), or with cancer, the virus reactivates and causes shingles. In most cases of shingles, however, a cause for the reactivation of the virus is never found. Anyone who has ever had chickenpox is at risk for the development of shingles, although it occurs most commonly in people over the age of 60. It has been estimated that up to 1,000,000 cases of shingles occur each year in the U.S.

The herpes virus that causes shingles and chickenpox is not the same as the herpes viruses that causes genital herpes (which can be sexually transmitted) or herpes mouth sores. Shingles is medically termed herpes zoster.

Home Treatments for Shingles

Shingles, or herpes zoster, is a painful skin condition that results from a reactivation of an infection with the varicella zoster virus, the same virus that is responsible for chickenpox. The virus is never fully cleared from the body after a bout with chickenpox, and it can reactivate to cause the nerve and skin inflammation characteristic of shingles often decades after the chickenpox.

Antiviral medications like acyclovir (Zovirax), valacyclovir (Valtrex), or famciclovir (Famvir) can reduce the severity and duration of the rash if started within 72 hours of the development of the skin rash, and pain medications like acetaminophen (Tylenol), ibuprofen (Advil), and naproxen (Aleve), and even narcotic pain-control medications may be useful in symptom control. In addition to medications, many people find that home care remedies can also provide relief for the pain of shingles.

Keeping the inflamed skin clean is essential, so wash the affected area with cool water and mild soap. Taking a bath or shower is fine. The blisters of shingles will crust over and fall off on their own, and it's important to avoid picking at the blisters to prevent the development of a secondary skin infection at the inflamed site. Cool compresses applied to the painful area after washing may be helpful. In the first few days of an attack, you can apply ice packs for 10 minutes at a time several times throughout the day.
