I have strange areas on my neck. I thought it was sunburn on my right side during Nascar Race..altho...I m not sure. That was about a month ago. Then there were dry rough patches along side of right side of face by ear/throat area. Next.....after time........same type of thing on left side. Nothing really big.....but....what is? I washed my hair Sat night with new shampoo.....got out of shower and red blotches on neck and throat area all around neck. What the heck? Someone told me allergy to shampoo. Ok......but.....last night it same back and then disappears. I just noticed - I can see rough dry marking on neck area. A little itchy but mostly not. What s going on?
