Most probably this swelling and gyno is caused by an excessive level of estrogen in the blood. Therefore, a first good step would be to start using an AI, such as Aromasin. It is the best AI you can get these days, and you will get a ton of benefits from it. The optimal dosage is 10 mgs EOD, but given your gyno problem, I would recommend you to use it at 10 mgs ED. Also, it would be a good idea to do blood work in order to know exactly what is happening there.
