Recently my nipples have been feeling quite sore. It's been going on for quite some time, and it's not linked to my period. I'm only 16 years old, so I'm not pregnant or anything. They feel quite sore to touch, it's almost like a burning feeling if I touch them, and it looks as if the skin is starting to crack and flake on my nipples :/ They look quite red as well. Also, there is no discharge.
I doubt it could be anything serious, I'm only getting more concerned because it's been going on for ages now and it's uncomfortable. Is there a reason why this could be happening?
