Gyno?

[Flexappeal]

So , I noticed today when I lift my arm up that I have this half dollar sized lump under my left nipple... No pain or sensitivity, feels like a hard muscle knot. I've done cycles before and I've never been prone to gyno. Currently I have been on RS-Transaderm for about 11 weeks. I just took 20 mg of tamoxifen and will continue it. Is gyno from RS trans possible?

Going to the doctor to check it out regardless. Just making me paranoid.. I did a trenazone run with RS trans a few months back.... I always run PCT.
