Im on TRT at a dose of 100mg wk, after about 4weeks or so I started developing a lump in my nipple. Its sensitive and sore if i touch, or push on it. So i got my labs done last week and my estrodial senstive was 21, which im told is perfect. My DHT was alittle high at 130. So what caused the lump? my DHT? and more importantly how do i fix this problem, what should i suggest to my Doc for him to prescribe?
