I have been treating my gyno with Letrozole for some time now and now curious to know when is it completely gone. Basically my symptoms are gone like the tenderness and sensitivity. If I press directly on my nipple I dont feel anything but when I squeeze around it and push in then it feels like there is a gland or its part of my pec or nipple. And when I lay down there isn't anything at all too. Only when Im upright do I feel that there is something behind my nipple but not directly behind it if you get what Im saying.
