Bumps around the nipple cna be from a combination of things. One could be that its form clothing that is rubbing the delicate area and another could be that it is a alergic reaction to a soap or perfume that you may have tried for the first time on your skin.
Those bumps are Montgomery glands, they can be white or have the same color as your areola (the brown area around your nipple). They're probably meant to lubricate your nipple and surrounding area, but nobody knows for sure.
