Gyno from winny?

I finished my first cycle about three months ago. Which was 25 shots of Zambon winny. Just the other day my left nipple started getting a little sore. Its been about a week and its started to get a little hard behind it. I thought winny does not aromatize?
I am getting Nolvadex in a couple days. Will the Nolva work? I also lost 7 pounds during this week, will the nolva help get any of the weight back and get the balls pumping. I am mostly concerned about the nips. Don't want man boobs!
