Shingles is a virus condition involving inflammation of sensory nerves that can result in severe pain. It causes localized pain, numbness, and itching, followed by the appearance of clustered blisters in a strip pattern on one side of the body. Sometimes the pain can persist for weeks, months, or years after the rash heals (known as postherpetic neuralgia).
The pain of shingles may develop even when there is no rash. The patient may notice several days to a week of burning pain and sensitive skin before the rash appears. In this situation it may be difficult to determine the cause of the often severe pain.
Other symptoms that may occur before shingles rash include fever, chills, upset stomach and headache.
