Hi, I recently noticed that only one of my areolas has changed colour and shape. It seems that the top half has had no changes but the bottom is more faded in colour now, it does not react to the cold as it usually would and overall the areola seems longer in shape than the second one due to not reacting to cold temperatures or touch. It also seems less sensitive when touched but in an uncomfortable way, as if it s slightly irritated. I am 18, no pregnancy before. I am on the pill to prevent menstrual issues but have been taking them for a year or so, so don t think it is the reason.
