I think you have to address this with your surgeon directly. Not being your surgeon or in the OR puts all of us here on this site at a disadvantage. Good luck.
It looks like you have a right breast swelling, which maybe a seroma or fluid collection. I have seen only two breast implant seromas in my practice, both were with textured gummy bear implants. I have been doing breast implant surgery for over 30 years. Best to see your plastic surgeon for a confirmatory examination. Hope your result improves and that your plastic surgeon can help you. good luck...
Without exactly knowing what and when your surgery was done, it's hard to make any definitive recommendations. If the right breast has changed in shape and size in recent times, you may want to consider a new fluid collection like a seroma or a simple capsular contracture. In my experience, I have never put one implant over and the other under as this will allow these implants to age in a different fashion. I would recommend that you go back to see your operating surgeon to discuss options for gaining better symmetry.
