What is the cause and possible cure for the million tiny white pimples on my chest and back?

I first had a break out a couple years ago after wearing a necklace made from nickel that my doctor said caused an allergic reaction. At that time my whole chest and shoulders were covered with millions of tiny white pimples. And this is the second time they've come back, but not as intense. They centralize just above my cleavage. Some are on my back. They don't itch and are not painful. I've tried astringent and witch hazel, but neither work. Any suggestions?What is the cause and possible cure for the million tiny white pimples on my chest and back?
caused by sweating


usually happens in sleep


the best things to do is make sure your sheets are washed often and keep hair out of the way of neck and shoulders so they get air to them


it might just be caused by hormones or something like thatWhat is the cause and possible cure for the million tiny white pimples on my chest and back?
