Flutter/gurgling after breast augmentation. Is this common?

Movement of fluid or air within the breast pocket at 2 days after breast augmentation is certainly possible.  However, I would recommend following up with your plastic surgeon to be sure there is nothing concerning going on.  Good communication between patient and surgeon both before and after surgery is very important.

Good question.  This is most likely fluid that will be resorbed by the body in a matter of days.  To be sure you should have your surgeon evaluate the situation.
