2 years post-op: have lumps that feel like balls, one each of my butt cheeks that have been causing me pain, are these scars ?

Hi and welcome to our forum!
At two years post surgery, the scars have healed. The nature of the masses is obscure. It could represent an area of increased scarring or the result of an organized hematoma or seroma. One cannot discern among these entities without examination.
As these masses are symptomatic, it may be wise to undergo in-person reevaluation by your plastic surgeon to determine their nature and advise appropriate treatment.

The first thing you should do is visit your surgeon. This is what postoperative appointments are for. During these appointments we discuss results and address complications and undesirable outcomes.None of us are going to be able to tell you what’s going on from posting on real self. This is not a good substitute for a proper surgical aftercare.My best guess is you have areas of fat necrosis. The only way to treat them successfully is the surgically remove the areas. A better option is to probably except them as a undesirabMy best guess is you have areas of fat necrosis. The only way to treat them successfully is to surgically remove the areas. A better option is to probably accept them as the outcome of your surgery.in the end it’s a balancing act of making an accurate diagnosis of what the problem is, determining how much it bothers the patient and what the patient is willing to go through to get some desirable changes.i’m sure your surgeon is happy to help you out. Best,Mats Hagstrom MD
