I went to the beach on Sunday and noticed that right in between my breast (where the cleavage is) it got really really red, almost like a sunburn, however it didn't hurt like a sunburn. It is now Thursday that I am posting this question and i am getting concerned because the redness is still there and now it looks like it's getting darker, there is no scarring, no peeling, nothing, just a red spot probably the size of a lime. What is this? Will it go away? Should I be putting coco butter or something on it ? HELP!
