Is swelling after blepharoplasty and facial fat transfer fat or am I swollen? (Photo)

Almost 3 months post op and I have a “bag” under one of my left eye never had them), and discoloration under both, after upper blepharoplasty and fat transfer to tear trough, upper cheeks and nasolabial lines. How can I determine if what I am seeing is swelling or something else that has resulted from the surgery? Also, regarding the fat transfer, how can I tell if what I am seeing is the “resulting” fat or if I am still swollen?
