Looks Like Shingles Shingles!!?

Shingles!!? - looks like shingles

On my back, I felt that my skin is painful when I was ... then the sensitivity in my leg (it's not my knee) when they are affected. But I also have muscle aches in the same place .... later, after a few days, see 3 small areas on the same leg that looks like a rash of small blisters .... I went to my doctor and he gave me a muscle relaxant and Motrin. I showed him the seats in the legs and said it was not herpes, I pulled a muscle .... But I saw my symptoms and my roof eruptions seems little 2 me .... My doctor is an idiot? ... Is it just a coincidence? .. I'm only 27 is too young for shingles ... I would like blood tests, if I'm too young for that? ... is back and leg pain from the symptoms of shingles, too? .. What is the cause .... Please help!
