Noticed 2 small, red bumps on my left breast all of a sudden. one right on the edge of the nipple and one on the skin. they are warm to the touch?

Skin eruptions/bumps: Thank you for your question. Red warm bumps on the breast area may be caused by many things. There are forms of inflammatory conditions of the skin that could cause a rash as well as responses to external & internal sources such allergies to agents or otherwise. Having an examination and evaluation performed by a qualified medical practitioner would be helpful in accurate diagnosis & treatment.
