It has been now 3-4 days, & i think i got rid of the swelling. I did not realize i had nasal arrithmia, until i was looking at the results from the Mayo clinic! I did not know what arrithmia was, so i looked it up, & it has to do with my heart. I had thought all along it was a heart condition/vasculitis. (guilian barre disease) Anyway, to no help from my PC, I was passing out, when i was having hard times breathing through my nose, plus using fairly high doses of oxygen.
