Hello, I had brain surgery to remove a tumor through my nose on Jan. 23, 2017. I just finished antibiotics Biaxin just this past Wednesday for a sinus infection. Stupid and I do mean stupid me used comet with bleach and scrub free spray with bleach together to clean. I have no sense of smell or taste because the nerve was damaged. I feel a burning in my nose. Not at the back of the nose, the beginning of it, I believe. My lungs and chest feel fine.
