Wow, you have come such a long way. I could very much relate to it as lived with one breast for two and a half years before undergoing reconstruction. I actually had a TRAM flap so can't comment on the air expanders. Having said that I do know one of the ladies in the Breast Reconstruction Online Group who had the air expander. The expansion process appears to be much quicker and much less painful than the traditional expanders. Maybe if you post this to that group you may hear from others who have had them. Whilst reconstruction is not for everyone it is a path that I am very glad that I underwent.
God bless "Brad" at your health fund. We're sometimes lucky as we go through all that comes with a breast cancer diagnosis that some people are quite respectful and not say insensitive things.
I wish you luck in this final phase of your treatment and that you rock that air expander,
