Hello to all, okay so I started HRT March 14, 2015. So far my nipples have a large slightly along with my areolas, they are also a bit raised from my chest. Just underneath my nipples I can feel a marble sized lump growing under each. My question is "generally" how large does this lump normally get and how long does it stay a lump if ever it changes before breast tissue starts to develop? One week after my first injection my nipples began to get tender, and now they are constantly sore. Thank you in advance!
