I had chicken pox as a kid and I got shingles today...the doctor told me if you had chicken pox as a kid it easier to get shingles when you are an adult. I been really stressed out due to other medical problems I think thats how I got it..
To clarify you are immune to catching shingles from someone if you had chicken pox.
You get shingles from having had chicken pox, the virus goes dormant and comes out latter, usually due to stress. When it comes out as shingles it is contagious to people who have not had chicken pox because it is the chick pox virus.
