What are signs and symptoms of shingles?
Signs and symptoms of shingles typically occur over one side of the face or body and may include:
- Pain, which can vary in intensity
- Burning sensation, numbness or tingling, and itching
- Raised red rash, which usually appears a few days after pain
- Multiple blisters, which appear in a stripe pattern and may contain fluid
- Fever, chills, and body ache
- Photophobia (sensitivity to light)
What is the treatment for shingles?
Treatment is most effective when begun within 72 hours of the appearance of a rash.

What are the complications of shingles?
Shingles can have complications that last long after the rash is gone and may occur if the infection has not been treated appropriately. Complications include:

- Loss of vision
- Postherpetic neuralgia (pain that lasts long after the infection resolves)
- Loss of hearing and balance problems
- Loss of taste
- Bacterial infection of the skin, causing increased swelling, redness, warmth, pain, tenderness, and pus formation
Can shingles be prevented?
The FDA has approved the Shingrix vaccine to prevent shingles. Shingrix is a newer vaccine recommended by the Centers for Disease Control and Prevention (CDC) that is 90% effective in preventing shingles. The vaccine is given in 2 doses 6 months apart.
As a recombinant vaccine, it is created by altering and purifying DNA that codes for a shingles virus antigen. This antigen produces an immune response to fight the virus.
