Can you have shingles more than once and what are some of the signs?

Possibly: But it takes a very long time. You get shingles because your immunity to chicken pox has waned, and you get a reactivation of the virus in a nerve. This process generally takes decades to happen, but if you had the shingles in your 40s, and now you are in your 70s or 80s, it is possible. However, you are unlikely to get the shingles more than once in a short time.

Shingles: Most people only Shingles once in a lifetime (if at all). However, it may reoccur. Most cases of shingles last 3 to 5 weeks. Usually 1 to 5 days after one experiences pain/burning in a specific area, a rash with blisters appears. This may take a week to 10 days to dry up & become crusty. Usually within a couple of weeks the scabs resolve. REF: https://www.nia.nih.gov/health/shingles#catch
