Crankin, hope you are better soon, and very glad you wasted no time in getting to the doc. Sure does sound like shingles, given your years of issues. Not fun. I don't know a whole lot about it except that a guy at work a couple of years ago had a pretty serious case and missed a lot of work. He eventually recovered, but it was nasty and painful for him.
