Possible double bubble 3 weeks post op? (Photo)

Yes something occurring in the bilateral inferior poles? Did you have previous surgery? Only fat grafts with rigotomies will correct in my opinion after 3 to 6 months healing.... 

Thank you for your post, and the photos are very helpful. I certainly see the issue that you are concerned about with regard to the left breast. That is what a version of the "double bubble" can look like. However, although it seems like an eternity, you really are still in the early stages of healing. I would continue to follow with your surgeon to help you through this process. Fat grafting is a possibility, and I would not consider that to be a "patch" necessarily. 

It does appear to be a double bubble.  This can be corrected with additional dissection in the area to release the tight band causing this.  It may be possible to perform as an office procedure but more than likely a trip to the OR is necessary since it is difficult to anesthetize this entire area with local.  First, though you it may be better to wait and let the implant stretch this tight band, it may improve gradually with time.
