Without photos, it is difficult to say. If you have a tight lower pole of the breast with herniated tissue through the areola, then you might have a tuberous breast.
Thank you for your question. However, without photos, it is not possible to render an opinion. Take photos from several feet away of your chest at chest-level from the front and sides. Then, repost your question.
Is this a breast deformation or do I have puffy nipples?
Thank you for your question. Unfortunately without a full series of photographs or an in-person examination it is difficult to offer definite advice. See a board certified plastic surgeon in consultation, they can best supply you with a diagnosis and treatment options.
Without photographs and your age it is difficult to tell. Please contact a surgeon certified by the American Board of Plastic Surgery who would be better suited to give you an opinion based on your question.
