I also had this - but it lasted for weeks (i get eczema all over them too), so it drove me crazy... and i scratched them until they bleed.
But first, did you change washing powders or fabric softners, or soap or body wash? because that night be a quick solution?
Any of those creams (amolin, lansinoh, benpathen should help). I used paw paw, and when it got back hydrocortisone cream fixed it up.
Also, maybe try some breast pads in your bra to stop the contact? Might help? Also, you can try bathing in like pintarsol (i think they have a better smelling anti-itch bath thing out now), can help. And using QV wash etc (i find hamiltons is better for my skin than QV), oil etc might help calm the skin down.
I find once the itch goes, sometimes i've iritated the skin around there so much i just keep scratching... But its so hard... My nipples/breasts are very itchy at the moment, so i know what you are going through
Also, try putting icepacks on the area, helps take away the itch when its really bad
