I had shingles back in 2008 which developed on my back along the bra line (very awkward at the time as couldn't wear one until the blisters recovered).
I've generally been itchy around there on and off over the years but recently it's been a lot worse, with small raised spots along the same area that come and go.
Could this be related to the shingles and the longer term affects that I've read people can get but instead of it being pain it's general irritation?
