Shingles blisters usually scab over in 7-10 days and disappear completely in two to four weeks. In most healthy people, the blisters leave no scars, and the pain and itching go away after a few weeks or months.
The pimples change to pus-filled blisters that break open and scab over in about 7 to 10 days. When the blisters are scabbed over, they begin to heal. The scabs usually heal and fall off about 2 to 4 weeks after the rash appears. Some people with shingles also may have a fever, headache, fatigue, or general achiness. In rare cases, a person can have the pain of shingles without getting a rash. Some people (usually older people) have more severe symptoms.
