Nipples

Okay so about my areolas. I had posted that they were irritated and hurting a lot. It's been a few days and they still hurt but when j was looking at them my areolas are getting darker like a black color. It's not the whole areolas it's like spotty.... I haven't had sex I've fooled around but that was like a month ago. So what do you guys think it is? I'm actually stressing out.
