Normal. You are describing normal skin appendages of the areola of the breast. These are oil glands and hair follicles. They can be prominent at times and then be less prominent depending on stimulation, hormonal effects and heat or cold. Unless there is redness, tenderness, drainage, streaking or other concern, just observer. Never fail to get it checked if you are concerned.
Montgomery glands. These are likely glands. They are harmless. Picking them can cause them to become infected.
