Shingles, or herpes zoster, is a viral infection that causes painful rashes and nerve damage.
Shingles is caused by the varicella-zoster virus, the same virus that causes chickenpox. If you have previously had chickenpox, the virus stays dormant in your body and can reactivate in your nerves later in life in the form of shingles.
The most common symptom of shingles is a painful, raised, or blistered rash. It may appear near the waist or on one side of the face, neck, chest, belly, or back. It can also sometimes show up on other parts of the body. Other symptoms that can appear before or along with the rash include:
- Deep, burning, or shooting nerve pain
- Itching or tingling
- Areas of reddish or discolored skin
- Fever
- Chills
- Headache
- A general feeling of being unwell
- An upset stomach
Some of the early symptoms of shingles, such as nerve pain and discoloration, can appear weeks before the rash. Other symptoms may show up in the days leading up to it. The rash turns into blisters about three to four days after it appears. Within about 10 days, the blisters dry out and turn into scabs. The scabs may take a few weeks to completely go away.
The most common complication of shingles is nerve pain that doesn’t go away when the rash does. This can last for months or years and can be extremely painful. Other complications of shingles include:
- Bacterial infection
- Vision loss from an eye infection
- Facial paralysis or Ramsay Hunt syndrome
- Hearing loss, tinnitus, and other hearing issues
- Brain inflammation
- Vertigo
- Pneumonia
A healthcare provider will diagnose shingles by learning about your symptoms and examining the rash. If the rash follows the areas of skin along a nerve and doesn’t cross the midline of your body, that is a clue that you have shingles. A healthcare provider may also send scrapings or a swab of fluid from the blisters to a lab for diagnosis.
There is no cure for shingles. However, a healthcare provider may recommend managing symptoms with:
- Antivirals
- Over-the-counter pain relievers
- Corticosteroids
If you have previously had chickenpox, you can reduce the risk of getting shingles by getting a shingles vaccine.
