This question is better asked of your plastic surgeon, in the setting of an office visit.Without photos and some additional info, it is not possible to offer any specific suggestion. All the best.
Hello there. You need to provide more information for me to comment. Photos would be helpful as well. Where is the swelling located? Is it constant or fluctuate (or change in size)? Is it soft or hard or uncomfortable? You should also ask your plastic surgeon to examine you.
