Ive had this bump for a while now i used to have chest acne most of it has gone away but one is bigger than acne, the skin is sorta reddish around the area and in the middle it just looks like raised skin its not really a whiteish color. It has no pain to it even if i try to pop it or scratch right in the middle. When i push it in nothing happens either. Dosent change color when i try to pop it either. I got it around the same exact time i was developing acne on my chest.
