Sorry to chime in late here...
I had surgery on my nose (septoplasty) several years ago to fix my crooked beak and repair some of the damage from getting it smashed so much in my teens. I was two hours early for the appointment to remove the plastic tubes-of-death that were sewn in. I saved everything that leaked from my nose during that time, in neutral buffered formalin. I even sectioned a few pieces of tissue, and stained them with hematoxylin and eosin. Makes pretty abstract art. Nose debris art. I can send pictures for all those interested.
Still, always problems with those two face holes.
Grain free diet definitely, without a doubt, helped me. Much less inflammation in the sinuses. Still that occasional seasonal gig, but not much else.
Just an anecdotal story, I know.
The gluten free beer made by Budweiser is nice, but it takes a six pack to break even a mild buz.
