...Saw an ad for that on TV. It said shingles can last as long as thirty days. I don't know where they got that idea. I got shingles back in Dec. 2004. The day of the big tsunami. It lasted until Easter. That was three months. It was on the left side of my stomach. To sleep at night, I laid my head on the dining room table. You just couldn't let anything touch those nerve endings. It still gives me a twinge now and then.
