I'm not sure what the Tiny Red Bumps you have on your chest are but soaking a cotton ball with Apple Cider Vinegar and applying the Apple Cider Vinegar to the Tiny Red Bumps on your chest can help them go away.
Applying some Calamine lotion to the red bumps can make them feel better and also help them to go away.
Another option is to apply some toothpaste to the tiny red bumps which can dry them out and help them fall off.
