Hi Mel, hope you are well. Here goes, I am currently just over 6 months HRT. Tenderness for me started within 2-3 weeks, and the location is directly behind the nipple, both sides.
Hugs must be very gentle or they ard quite painful. Breast pain, i really did not experiance much pain at all, just a bit of a itch on my right boob, on the side.
Nipples have grown a bit, and respond more to touch and temperature, complaints though...
General growth, not extremely much, but something. Measurements seem a bit deceiving, but be aware that even is a measurement seems to stay the same, body changes on the opposite side may well compensate for it. (Boobs growing, but fat and muscle on the sides and back might be reducing.
