if my nipples are not nipples will be sensitive and itchy but just puffy and really looks like gyno, does this mean i have it or not?

i was thinkin it could be water weight or maybe becuz my cals are up to nearly 3000 that is making my chest look like it have gyno?, cuz i have some fat already..

i'v started taking 40mg of Nolvadex just incase, is this the right thing to do tho if i aint got sore nipples?
