Air Xpander with remote control

Hi all, I'm using the Air Xpander in my R breast only and I'm 8 weeks post op having a total mastecomy.   No hospital trips or yucky needles for me thank goodness.  It's day 4 of expansion and so far so good, except today the remote doesn't want to work and has locked me out!  So now have to wait 4 days b4 next appt with ps. I have no pain, just a little uncomfortable under my arm, as It still feels like I have a packed lunch under there, lol.  I have only had 130cc put in so far and it's very hard already.  Not sure if my ps had already put some in while procedure was being done.  My total amount is suppose to be 560cc, so now not sure if I want to go that far as I can't possible imagine how that is going to feel.  Anyone else at the same stage?  How are you coping with it?
