It sounds to me as if everything is typical for a cheek implant recovery. If you are satisfied with one side and assuming the surgeon used the same size on the other and as la_angel pointed out that your face is symmetrical according to average standards, I believe the swelling on the larger side will subside. It's important to note that with cheek implants the swelling will feel hard as if it feels like the implant. Please keep in mind this is normal and fortunately it is most likely a degree of swelling you are feeling instead.
“One popular new plastic surgery technique is called lip grafting, or "fat recycling" wherein fat cells are removed from one part of your body that is too large, such as your buttocks, and injected into your lips; people will then be literally kissing ass.”
