Praise God! That must feel so good to have the hump gone and your shoulders straight and not be leaning sideways anymore! Wow, I can't even imagine. I'll bet it feels a lot different now when you sit back in your chair! Do you have more lung capacity now, too?
I'm glad to hear you're moving a lot and practicing keeping your neck straight. Does it get stiff sometimes? Mine did for a little while, which I wasn't expecting since it didn't get fused (my fusion went from T3-L1), but then again it did get un-scrunched quite a bit during the surgery and it was probably adjusting to that.
