After getting surgery. One side feels like a normal boob. Whereas the other side feels like I have an implant. Why?

Without a preoperative
and postoperative exam and seeing your operative note, this would be
impossible to tell. Early on in the several weeks following surgery there is
often a difference that resolves itself. Whether this applies to you is
unclear. I recommend you discuss this with your plastic surgeon.The final appearance, shape, and movement are not exactly the same as normal breasts. The surgically enlarged breasts do not move in the same way as normal breasts. They tend to be firmer. The contours are usually somewhat different than normal breasts. In some patients these discrepancies may be rather noticeable. Although every effort is made to place the implants symmetrically, complete symmetry is rarely achieved. Immediately after surgery, the breasts are swollen and firmer. The final shape and size is approximated after 2 to 3 months, but up to one year may be required for the end result.

Your plastic surgeon will always be your best resource when it comes to specific/meaningful evaluation, advise, and/or reassurance. Having said that, it is not unusual for breasts to demonstrate some degree of visual/"feel” asymmetry after breast augmentation surgery. Many of my patients, on average about 3 months after surgery, report that there breast implants feel “part of me”. Again, best to follow up with your plastic surgeon for specifics.  Best wishes.

This is a difficult question answer without pictures or a physical examination. I go back to your plastic surgeon and pose this question to him or her
