I have white spots, puffed scars mainly on my chest, shoulders and back. I also have random white puffy scars on various places on my body. I have seen several dermatologists and was told different things each time, they are acne scars, it is a fungus, they have no idea etc. I am having a hard time believing that these are simply acne scars, they show up in places where I have never even had acne like on a forearm, lower back or neck as well. I have seen new white bumps on neck. Please help?
