I am two days post op. Received 240cc in silicone implants.
At two days you may only have more swelling on one side or if your implants are under the muscle, one side may have a little more spasm. However, I would contact your surgeon to make sure you do not have a hematoma.
Early after surgery one breast can be more full and tighter than the other. Usually it's simply different swelling and muscle tightness. This will change as time passes. As long as it isn't getting increasingly big and more painful than the other side everything should be fine. If it does change significantly call your surgeon to discuss
