In all probability the small pea sized
lump or lumps
under or around the
nipple are areolar skin glands or Montgomery glands. They are normal findings at puberty. However, if the lump is painful or increasing in size or causing redness, then this could be an infected hair root. In this case, you would need to consult a doctor immediately. If the lump is painless, not bothering you at all, then please do not touch it or squeeze it.
