Good day. I would like to know the reason why my gyno seems to come back after being gone for so long. I did a steroid cycle back in 2012 . At the end of the cycle, I used Nolvadex 40mg every day for two weeks. Every after few months it will come back. Now it had been 1yr 5months since it happened and I can feel that my right nipple is acting up again. the doctor said it's mastitis but I doubt it since the antibiotic. they issue dont work. Any advice? Thank you in advanced
