I am very worried.
It is fairly common for breasts to heal at a different rate. You are early in your recovery, it may take several more months before you see your final result. try to be patient and follow your surgeon's post operative instructions. Good luck.
There are many variables when it comes to how much breast implants will "settle"; the main variable in my opinion will be exactly how/where the breast implant pocket was dissected. For this reason, your plastic surgeon will be your best resource. Generally speaking, breast implants will "drop" into the pocket that was created during surgery. The rate of breast implant "settling" may depend on factors such as size of breast implant pocket dissected, tightness of the overlying skin/muscle layers, and size of breast implant utilized. Some degree of asymmetrical "settling" is commonly seen. It may take about 6 months (for some patients longer) to see the final result. As the breast implants "settle", the lower breast poles will round out, and the nipple/areola complexes will sit higher on each breast mound.In cases where significant breast asymmetry persists, the pros/cons associated with revisionary breast surgery (for example, capsulotomy surgery for an implant that is sitting too high or capsulorraphy for a breast implant that is too low) should be carefully considered prior to making decisions whether or not to undergo further surgery. Best wishes for an outcome that you will be very pleased with.
