Hi, I'm almost 17 years old and I noticed this yesterday. I was wearing something similar to a cutlet in my bra and was quite active with it. One site suggested to someone with a similar problem that it might be chapped, so last night I put lotion on it and went to bed without a top or bra. Yesterday the areolas and nipples were tender to the touch, there were some small bumps near the nipple, puffer ones further away from it on the areola, and peeling skin around the outlines of my boobs and on the areolas and nipples. Today, after the lotion and lack of smothering/rubbing, the puffier bumps went down, but now almost the whole areola seems to be swollen or puffier. The few little bumps around the nipple went down a little bit, but when erect those bumps are a lot more prominent, appearing as they were last night. The area is still tender to the touch. I'm really hoping this isn't serious, since it happened so fast and all...
