Very swollen & red nose 3+ years after rhinoplasty

I had the surgery done over 3 years ago, & ive been getting swollen/red for about 8 months now. I’ve seen an allergist, my surgeon, & multiple dermatologists. Nobody knows what is going on. Exercising, heat, low humidity, high sodium meals all trigger it badly. It practically doubles in size & gets really red. What could this be? Only thing I haven’t tried was steroid injections & Isotretinoin. My derm thinks it’s morbihan’s disease. It’s difficult to breathe during a trigger.
