Thank you for the question and photos. It is rather difficult to fully assess your situation without an in-person exam. Typically, some swelling, scarring, and discomfort is not uncommon after a tummy tuck. However, considering that you had your procedure approximately 2 years ago, the healing process should be complete at this point. It is possible that you may have developed a cyst.It would always be best to visit your board-certified plastic surgeon to evaluate your needs and obtain a reliable medical advice. Best of luck!
