Swelling 4 years after rhinoplasty tip graft, could lymphatic system be damaged?

Four years ago I had a fascia graft to my nasal tip - after an initial procedure that did not touch the tip. To this day, the tip continues to swell up and down constantly. It can be triggered by almost anything - heat/humidity, cold, alcohol, sleep, exercise, air travel. My belief is that the procedure either damaged the lymphatic system in my nose, or scar tissue is disrupting lymphatic drainage. 1) Do you agree that this is a likely cause? 2) How can it be permanently resolved?
