I have a rash on my chest, neck , and one upper arm . The spots are shiny, smooth, very light pink, do not itch . After sun exposure they are now white. It has spread a little on my chest (which are pink). Some days I don t really see the pink spots, some days I do. The white ones are just faintly there. I have no idea what it could be, any ideas? I have no insurance so I would like to try a home remedy before paying for a doctor visit.
