Without treatment, the symptoms of
shingles (eg,
rash, blisters, and pain) usually go away in about 3 to 5 weeks. Although
shingles can make you very uncomfortable while you have it, it usually is not dangerous to healthy people. However, some people may develop complications from shingles, such as continued severe pain after the blisters are gone. This condition is called postherpetic neuralgia (PHN), and can be extremely painful and very hard to cope with.
