Alright well its not out of control yet. My left nipple has alittle knot behind it and is fairly sore. It is also kinda of swollen but not anything to run off into surgery. Im wondering what the best way to treat it would be. Ive been running 30mg nolva ed since it started and im not sure if its stopped. Neways whats the next step? Arimidex is common but ive heard its expensive. Also the Letro from arr.com is said to be more effective but is cheap. Is it the real deal and will it help me with stopping the swelling and soreness?
