I have flu like symptoms after my rhinoplasty, could my surgery be the cause?

Rhinoplasty in 2011 now have trouble breathing and sick ever since. Deviated septum w/enlarged turbinates since birth, I always have the flu, cold after taking a shower or walking 30 min symptoms get worse. Flu like, w/ extreme fatigue, ear pain & brain fog. I have an autoimmune disease hashimoto since 2011 being treated w/medication but not the cause. Could these symptoms are because of my nose problems? Do I need to think about a virus/immunesystem? I tested for sinus problems there is nothing to see.
