Feeling knots after liposuction is common and should go away with time but it takes patience. Typically swelling takes about 3 months to go down but the knots can take longer. Keep an eye on it and follow up with your surgeon if it doesn't resolve within a year. ac
I empathize with your concerns. However, I cannot comment specifically on your condition since "got upper/lower abdomen done" doesn't tell me anything about what kind of surgery was performed. Liposuction? Abdominoplasty? Both? Generally speaking, swelling is not uncommon...
Firmness can last about 6-8 weeks or longer as your body recovers. Good work on performing massage and compresses. If the firmness doesn't go away, please see your surgeon to discuss your results. You may want to ask them now about what you can do to soften areas of concern.
