I had chicken pox when I was about 8 years old, and it was a pretty severe case. From what I know it is possible to get them again, but unlikely. This past weekend I was in my cousin's hot tub and today I hve red bumps all over my arms, torso, butt, legs and back. I do remember when I was little I was in a hot tub before I got them. I think it could just be swimmers itch, they are itchy, but they are sore if I touch them aswell. Some of them look like they have a little head as well, like youcould pop them. So I was wondering what chicken pox look like in the earliest stages as I cant remember at all, and is it very likely I got them again? Could it be from viruses in the hot tub?
