Are shingles really a sign that I have HIV??? Please help?

I'm a young person (I like to think healthy young person) but recently my doctor prescribed me with shingles. So I looked at some websites and said that it was rare to have it at a young age anyway, and then it said "Shingles also may be an early signal of HIV infection, especially when it occurs in a younger person" is this true?? Does taht mean I'm not healthy?
