Shingles follows a pattern: 1  The first sign is often burning or tingling pain; sometimes, it includes numbness or itching on one side of the body. 2  Somewhere between 1 and 5 days after the tingling or burning feeling on the skin, a red rash will appear. 3  A few days later, the rash will turn into fluid-filled blisters.
In this case, the nerve involvement causes pain and extreme sensitivity, but the rash just never shows up. Usually with shingles, once the pain sets in, it can last for up to three days before the rash appears. Sometimes this period of pain before breakout lasts longer  the severe pain associated with shingles can continue for weeks, even months, before there's a rash.
