HI, about two weeks ago I went a pick up pallets. After I felt itching and burning all over my skin, It felt as if I had Insulation on my skin, then I noticed that I had a couple of red pimples just underneath my left butt cheek. In the weeks prior I have been experiencing back pain, stabbing pain, numbing and tingling. I then had the little pimples form on my chin, it scabbed up and I left it alone. Today the pimples are back underneath my left cheek and I see a bunch of little pimples on my back, shoulders and my forehead. Can this be shingles?
