Itchy boob!

Victoria

Hey guys so for about 6months ish my left boob has just been driving me crazy! Randomly it will just start to itch so bad and its only that one. it doesnt hurt or anything but its so annoying. i got an ultrasound on it a couple weeks ago and the results came back fine and no cysts or tumors 🙌🏼🙏🏼but any ideas of what it would be or how to stop it?
