Shingles is not something you want to contract, it's very painful and there is no effective treatment other than to let it run its course, which may amount to many weeks. Never had it but those close to me have, and it wasn't pretty.
There is an antiviral treatment that helps to clear up the disease faster. I took the antiviral, although I am not sure if it really made the rashes go away faster. I continued to have sharp stabbing pains on the side of my neck long after the rashes cleared up.
