If you catch it fast it can be really mild. Good idea to look up pictures of early stage shingles on the internet so that if you notice anything like that you can hightail it to the doctor. The whole thing was over in less than a week and I only had a bit of pain on day one. So if treated immediately, I don't think it is anything to really worry about. I had been dreading the possibility knowing how common it is, and maybe I was lucky too, but it was a very mild experience.
