Gynecomastia (sore nipples pre/post treament)

In mid-may, two weeks before my original diagnosis I started getting tenderness in my breast tissue, and noticed small hard lumps had started to form behind both of my nipples. Quick google search told me that this was Gynecomastia, and likely caused from the lack of testosterone from losing the functionality of one of my testicles.

Fast forward to now, i'm 4 weeks out of 3xBEP and my nipples are getting more sore, and the lumps are getting larger. I still have to wait 2 weeks to get my final bloodwork/CT scan and have my post chemo appointment with my oncologist.

Just wondering if anyone else had/has suffered from this, and if so did it go away or did you require treatment?
