It's oe of a few: Things. It could be a lymph node, breast tissue or infected hair follicle. It's hard to say for sure why it gets painful with menses and otherwise ok unless it responds to hormones. It could be hat u have breast pain and feel it more there b/c of generalized soreness. I would get seen, may improve with simple birth control pill, may need a biopsy, not breast cancer at your age though.

See doctor: How long has this been going on? There are many reasons a person might have a tender lump in your armpit. A thorough history and physical will help your doctor decide how this needs to be treated. Call for an appointment.
