Late getting to a response.

I meant saturate a clean cotton ball with H202 and then put it in your nose for about five minutes (do not inhale it) - breathe through your mouth.

Then remove and clean your nose out (flush it out) and you should be breathing fine the rest of the day.

Thank you for the tip. Inexpensive and worth a try!
