Hi, they could be just normal hair folicles that got impacted or something, or it might be molluscum. One of the signs of molluscum is when you squeeze the bump, a hard thing comes out...if there are hairs growing out of the middle of the bumps, I wouldn't worry as they much just be irritated or clogged folicles, but if not, I would probably go to a doctor and ask about molluscum. If it it molluscum, it's not really a big deal, its a benign condition, just bothersome. People ususally have one outbreak of the bumps, which can last over a year, but when they go away, they dont usually come back. They can be excised, or aldara cream makes them go away too. Good luck, it's probably just hair folicles.
