I started feeling chaffed/ or like a mild sunburn since sunday. it runs along my under arm and comes across my side to one side of my breat and it also goes across my back. It actually feels like i ve gotten chafe with this cold weather. But I don t see any red marks where I feel the burning. I actually thought iy could have been chaffing from a bra because thats where it feels coming from but the thing is I don t see any red chafe msrks. The weird thing is it only bothers me on 1 side I guess my question would be if this is shingles can you have these symptym for a while before the rash and blisters start
