Hello dear, thanks for your question and provided information as well..
The breasts may lose their elasticity and firmness which can be caused by different factors such as pregnancy, massive weight loss, lactation and aging. To reaffirm the breasts and restore the natural look your surgeon can perform a mastopexy or breast lift. A breast lift restores a firmer, perkier, and more aesthetically pleasing shape to sagging breasts. This not only can improve a patient’s appearance by restoring her youthful, feminine proportions, but also help bras and swimsuits fit more comfortably and attractively. By removing excess, stretched out skin, reshaping the breast tissue, and raising the nipple & areola into a more forward position, a cosmetic surgeon can create a more youthful breast contour. Stretched, large areolae can also be reduced during breast lift surgery, creating an overall better proportioned, natural looking breast, Actually the perkiness on a person or another, depends on patients skin and breast tissue..
You are still very early in the healing process. You have to give it time for them to settle. Any specific concerns should be addressed by your surgeon.
Some patients with submuscular implants have spasm that last a few days to a few weeks which elevates their implants. Often one side more than the other and since the muscle is attached to your arm, the side used more could elevate more. Follow closely with your surgeon and hopefully time will resolve this. Good luck.
You should trust your doctor and get help from her/him unless your doctor abandoned you. Your doctor is the best person in the world who knows what have been done in your breasts.
