    What is the outlook for Shingles ?
    ### Response:
    For most healthy people who receive treatment soon after the outbreak of blisters, the lesions heal, the pain subsides within 3 to 5 weeks, and the blisters often leave no scars. However, shingles is a serious threat in immunosuppressed individuals  for example, those with HIV infection or who are receiving cancer treatments that can weaken their immune systems.
