About 4 years ago I started getting these light tan spots around where my bra line is. I wasnt too worried about to begin with because I thought it may just be heat rash or something. Well, about a week ago the flared up into red dry spots and started spreading to my arm, leg, and finger and they itch. It kinda looks like exzema but I dont know if it can spread like that and my husband noticed that he had one on his cheast. I have been tested for std's and they came up negitive so I dont think it can be that. I'm making a doctors appointment for next week to see if they can tell me what it is but I just wanted someone's input before I went.
