Shingles, or herpes zoster, is a result of the varicella zoster virus (VZV), which is the same virus that causes chickenpox.
Shingles presents as a painful rash that may look like a stripe of blisters. It often appears on the trunk of the body or on the face. Pain can persist even after the rash is gone (this is called postherpetic neuralgia).
Ozone therapy has proven to be an effective treatment, relieving the pain of shingles and postherpetic neuralgia.
