Without seeing any photos or more details about the timeline of your procedure there are some basic tips about the healing process that are provided to my patients:
Most patients will be placed in an abdominal binder, which they will wear the first week. There is usually a fair amount of swelling and the binder should be opened several times a day so that there are no pressure points. After the first 7 to 10 days the patient is placed in an elastic garment for compression over the next six weeks.
Swelling can persist for several months and will gradually improve and will look better at three months, six months, and even one year. Frequently the pubic area and the scrotal and penis area for men can become very swollen and discolored during the first two weeks due to gravity as this is the lowest area for swelling to accumulate.
You can return to full activity without restrictions at 6 weeks, including workouts to continue tightening your abs.
If you find yourself concerned at all about your result or healing it would be best to visit your surgeon to have the area examined and make sure that healing is progressing well. Good luck.
