Can lip filler damage lymphatic drainage system years later?

I got Juvederm 5 years ago. My lips went gradually back to original size but the area between my nose and upper lip is puffy. I assumed it was from lip filler migration. My plastic surgeon said the trauma from the injection damaged the lymphatic drainage irreversibly which caused lymph fluid buildup. Can this be the case or is it likely residual filler blocking the lymph drainage? Does it make sense to try dissolving 5 years later? Why are my lips small but the non injected area puffy?
