3 months after a cycle?? usually estrogen rebound only occurs either during pct or right after it 1) did you do a good pct? 2) you sure it's not in your head? I've noticed that your bf% as well as diet can have a pretty big impact on how your nipples look like. If I eat really bad foods for a few days I tend to notice my nips hold a little more water than normal and can result in thinking "oh crap I have gyno". But then I up the cardio and broccli resulting in less water weight and no more puffiness. real gyno hurts really bad and gives you firm glandular tissue that develops under your nips. You'll know for sure once you actually get it. If you want to take drugs....the only thing I could suggest would be to run nolvadex at 20/20/10/10 for 4 weeks and see if that does anything. If not, then letro should be a surefire way to at least reduce it. If you really really want to know for sure if something is up, get your blood drawn to see what your test and estrogen levels are at. If they are fine (which they prob are by now) you're tweaking.... if not then get on pct meds
