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.
Done with that, the area dries up and the crust gets removed eventually. Thus how long does shingles last is up to 3 to 4 weeks. The rash may also be present on a personâs face, ears, mouth, forehead and even eyes. It is quite painful and can burn too.
