I am 38 up until 10 years ago I was a dedicated sun bather. This year I have tanned one time. No burning ad I am very olive. But for about 9 months my shoulders and back are dotted with the tan ski. And dots of very pale skin. No flaking or dryness. Not raised or even palpable. My neck is covered in bumps, resemblibg pimples. I pick and pop them.could this be shingles? Suffered almost fatal case of sepsis 1 year ago. Please help.
