Most people recover completely from an acute episode with no pain; and skin color returns to normal. Once you have had shingles, it is unusual for the condition to return. Shingles comes back in only about 2% of people, but in up to 20% of people with AIDS. Long-term complications from shingles, such as post-herpetic neuralgia, may continue for months or many years. The disease also may cause varying degrees of skin discoloration, primarily darkening.
