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.
When a person is getting over shingles that are on their body, the blisters start to crust over, and the pain and irritation tend to disappear over a period of one to three weeks. When the shingles virus damages a nerve, you can have pain or tingling for months or even years after the actual blister rash has healed.
