Hi Oskygirl. I had a mastectomy and lat flap reconstruction on Jan 17, 2012. It's been almost 6 months and I'm doing great and do not experience any pain yet I often do experience some discomfort. I think it took me about 2 months after the surgery to feel okay and not be in that much pain although the weekly tissue expander treatments were somewhat painful but not all the time.
One thing I'm not crazy about is the thickness of the muscle that is removed from the back and pulled around my side to my front and used for the reconstruction. I also do not like how my reconstructed breast is now a "muscle" and acts like one and expands and tightens as a muscle.
I also had 7 lymph nodes removed so I have other issues with my arm from that surgery but overall, I'm pleased with my reconstruction although it's not completed yet.
