Painful nipples?

Posting anonymous cuz I’m not brave. 😔

But as of late, like the last week, my nipples have been really really sensitive. They hurt if I touch them too much, but generally they feel good? I mean before this last week I couldn’t feel any sort of pleasure from touching them, but now I do, even though it really quickly starts to hurt. They’re hard pretty much all the time. They aren’t leaking or anything, no pus or discharge, and I haven’t felt any irregular lumps in my chest either. I’m not horny or anything, they’re just always raring and ready to go. They aren’t hot, or inflamed, there’s no swelling, they only get warmer if I play with them or something. I cannot figure out why this is happening for the LIFE of me. It isn’t irritating and I don’t think about it much unless I accidentally brush against them. I wonder if maybe I’ve gotten some dirt in the tips but then there would be discharge, right?

Should I see a doctor? PS. I’m not on my period and my “fertile window” or whatever is over.
