Many women have back pain related to their breast size. If you have large, drooping, or heavy breasts, that can contribute to stiffness in your neck, shoulders, and back. A breast lift can slightly reduce the size of your breasts, but the weight difference likely won’t be significant.
However, lifting the breasts may help you maintain a better posture. When your breasts aren’t in the way, it can also make physical activity easier. You might find it’s more comfortable to build up your core strength or go to that yoga class which could, in turn, reduce pain.
