Persistent oedema under my eyes 9 months after blepharoplasty

Hello, 9 months after blepharoplasty and swelling under my eyes won't go down. Doctor says that this is not because of surgery , but I never had such bags under my eyes before surgery. Nothing helps and I did manual massages for lymphatique drainage, Accent Prime procedures, i took Diuretics, no change. I'm desperate for other opinions. Will this ever go away? What can be done to solve my probem? Should a correction surgery be done? Thank you very much all for your reponses.
