Swelling is unavoidable after surgery. The amount of swelling can vary based on many factors. If you have a very tight and developed pec muscle, if you overdo it, overuse one arm, or if you don't limit your activity your first two weeks post op, your risk of swelling greatly increases. The most important way to minimize swelling is to restrict your activity per Dr. Feldman’s instructions and wear the garments provided. Swelling significantly more on one side than the other is a clear indication of overdoing it. Overdoing it increases your risk of bleeding, bruising, capsular contracture, and implant malposition. Swelling typically peaks 48-72 hours after surgery, around the time of your post-op appointment, and slowly resolves over the next 8-12 weeks. Overuse will increase both, the amount, and duration of swelling as well as discomfort. As the swelling resolves, the upper part of your breast will appear prettier, softer and more natural. This is the fluffing portion of what woman refer to as the “dropping and fluffing” that occurs approximately 8-12 weeks after surgery.
