What is this, folliculitis?

For the past year ive had these blocked up follicles all over my legs and my waist... I've kept getting diagnosed as having folliculitis but I don't think that's what it is because it doesn't itch at all... does anyone else have pimple-like pustule type things in their hair follicles? I really want to clear this up because it deeply interferes with my life when it comes to confidence.. being that I'm only 16.
