Sorry to hear that man, I had gyno surgery last november.
There is some debate as to whether you can get rid of the lumps once you have them. Some people claim that you can get small lumps to go away with nolvadex or arimidex treatment. However, neither worked forme. I had never had any problems with nips while cycling. Well, much to my dismay, about one month after a heavy deca/test cycle, my nips hurt so bad that I could not even bear to have my shirt touch them. It was too late. I now use arimidex on each cycle and keep a supply of nolvadex just in case.
Goodluck...if you have questions about the surgery, pm me or do a search.
