I have shingles. I've had it a couple of weeks. I'm due to go and see the doctor in early November, so if it hasn't cleared up by then I'll ask her opinion.
UK health websites tell you it might clear up in a couple of weeks, and that you need to see the doctor if the vesicles are near your eyes.
In my case I have four red, raised itchy spots, perfectly symmetrically arranged, one on each shoulder blade and another on each side further down my back.
