Why Am I Getting Rashes On Waist And Knee?

I had sensitive skin for a couple of days , then broke out in two areas of rash that looked like blisters. I went to a nurse practitioner who believes I have shingles. My skin sometimes hurts, my body sometimes hurts in that area and I continue to have extremely sensitive skin that comes and goes on one side of my body from my waist to my knee. The rash is on my hip and a small part of my beltline.
