Is It Normal for One Breast To Swell More than the Other After Breast Augmentation?

Thank you for your question. Congrats on the surgery. It may take months for the breasts to soften and settle, and they may never soften to the pre-surgical state. In addition, the greater the implant to breast tissue ratio, the more the implant will affect the longterm firmness (or softness) of the breast.  It is also normal for one breast to soften before the other.  I would exercise patience and see how things change with every few weeks that pass by.  I would continue to follow up with your surgeon closely during the healing process.

It is very common for one breast to be affected by swelling or than the other. Swelling usually subsides within a few weeks after surgery. While it is difficult to say what size you will actually be after the swelling subsides you will most likely be around the size you wanted to be since the implants were selected for that purpose. 

Your breasts may swll differently after surgery and in particular the position of your implants with one higher than the other is even more common.  This will improve in short order.  However, your uneven swelling may also represent a hematoma or blood collection.  Make sure you see you plastic surgeon regularly to be evaluated.
