Please Help!

Girls.. So lately my nipples have become itchy af then the last 2 weeks my nipples have become extremely sensitive, always hard and hurt like hell😣. When I'm in the shower I have to cover them, I can't let anything brush past them or it'll hurt. It's weird because it's both nipples.

Does anyone have any idea what this could be?

*Also I have taken a pt - it was negative*
