Had some months (5 - 10) that itched, nipples mostly and being pretty sensitive. Even walking down steps at normal pace, not hopping or skipping. Solution? Grab your noobies and make up for the bra I was not wearing.
Jogging at that time! OUCH! Not so appreciated to hold them for support in public - I did get odd looks :-) Sports bra worked wonders but also looking flat as a pan cake - can't have it all, um.
Having had to go off E for my planned GRS (disaster struck and I had to re-schedule, sob!) left my noobies as robust as a guy's. Now after going back on E, only Estradiol valerate at present, so far no growth itch and pains at all. *But now they sure do like to be cuddled*, lots! now they not hurting. Yummy boobies if relaxed, um. Something to really look forward to for you, promis :-)
