Sorry to hear about your problems. I think that first guy you saw who poked you twice is a dork lol.
About your nipple discharge....At the age of 20 I began having a greenish - black discharge from my breasts, left more than right. They never did a mammogram on me for that but did express some from my breasts and sent it to the lab for evaluation. I had severe fibrocystic disease and that was about all they did. They told me to quit squeezing my breasts. LOL well easy for them to say but I finally did. I got tired of the same ole stupid answers. But mine was fine.
40 yrs later I was diagnosed with breast cancer on the left. But the discharge finally stopped after many years (like when I was 50 not sure). I would say the best kind of doc to see for that is a breast care center doctor, they are awesome.
Not sure this has helped but good luck!!!!
Hugs, love and prayers,
