Shingles is not usually dangerous to healthy individuals although it can cause great misery during an attack. Very rarely, shingles can lead to pneumonia, hearing problems, blindness, brain inflammation (encephalitis) or death. For about one person in five, severe pain can continue even after the rash clears up.
Can shingles go away by itself?
In most cases, the rash and these unpleasant sensations eventually go away, even without treatment. Sometimes, however, post-herpetic neuralgia causes pain for a long time after the rash has gone. Acetaminophen (Tylenol) is a pain reliever and fever reducer. It will not change the risk of complications from shingles.
How long does it take a shingles rash to go away?
Somewhere between 1 and 5 days after the tingling or burning feeling on the skin, a red rash will appear. A few days later, the rash will turn into fluid-filled blisters. About a week to 10 days after that, the blisters dry up and crust over. A couple of weeks later, the scabs clear up.
