Thank you for your question. This swelling could have different etiologies, such as post operative edema, seroma, hematoma, dehiscence of the fascial sutures, etc. It is not possible to make the diagnosis without an in-person examination. Having said that, You are very early in the healing process at this point. Healing from surgery will take time. In the initial phase after surgery, within the first three months, there is a period of inflammation and scarring that must occur in order for you to heal. Over ensuing months these processes will subside and the inflammatory process gives way to scar softening and remodeling. It is during this time that you will start to see your results appear. I tell my patients that they will not see their final results for at least to 6 months.I would recommend to continue close follow up with your plastic surgeon as they are in the best position to evaluate and treat you during your post operative recovery. This will allow you and your surgeon the chance to discuss your concerns and help allay any anxieties you may be experiencing. Best wishes.
