“Still too big after breast reduction surgery”

Seeking help:

I had breast reduction surgery one week ago. My breasts were supposed to be reduced to a B-C cup from a DD but they are still Ds one week later. Are they swollen , will they get smaller in the next few weeks. While the lift looks good , I am disappointed and concerned that insurance will not pay do to the size I was left with and my neck will still hurt? I asked my doct why they are larger than expected, he explained something about the elaciticty issues with my skin that kept him from being able to reduce me further than he did. I still dont understand please explain>
