Hey hun, the hunchback thing is completely normal and does go after a few weeks! I was constantly walking hunched over because when I straightened my back, my front used to throb- probably from all the skin stretching and the new weight etc. It definitely goes, trust me. As for the sports bra, stick with it- you need firm support in the first month at least. xx
As said above hun its totally normal, we walk as if we are protective of our new boobs, plus it hurts more to stand up straight coz it pulls on your chest I was like it for about 3 weeks xx
