Hey bro, first of all, in case you don't understand what happened. you experienced an estrogen rebound. This is very common to have happen. The solution is to taper down the AI when you are ready to come off of it. Not sure if you did a PCT but I would suggest to after every cycle. Clomid or nolvadex will bind to the estrgoen receptor and keep you from getting gyno, no matter how high your estrogen goes.
At this stage, I would suggest taking Nolvadex 40mg untul it goes away. Then stay on 20mg for 3 monre weeks. Once you have developed a lump, it will not go away without an opp to have it cut out. That being said, you can manage it. Stay on an AI through your whole cycle, then continue on it through the first could weeks PCT at a lower dose than normal. There are a lot of guys that have gyno but you will never know becuase it is very small.
