Ok I have been off a cycle for 7 months did my clomid Nolva and hcg..........everything was fine........Blood work done in begining of Dec all good.........Now for the last 2 weeks my nipple was hurting like a weird throbing and burning feeling...........Last Night I took my shirt off and noticed a lump right above my nipple about the size of a 22 bullet......And it hurts .....Now I figured gyno is developing......Have Arimidex and Nolva..........What should I use and how many Mg should I start out with...........I never had a problem with any signs of gyno while on cycles ...........Why 7 months later and how can I be sure it is gyno and not something more serious...Like the BIG C
