Lidocaine patches are used to relieve the pain of post-herpetic neuralgia (PHN; the burning, stabbing pains, or aches that may last for months or years after a shingles infection). Lidocaine is in a class of medications called local anesthetics. It works by stopping nerves from sending pain signals. Call us at 704-503-9338
