In theory, ozone damage to the cells lining your nasal pathways could indeed be responsible for your temporary pain.

However it should be pointed out that people are very sensitive to smelling ozone. We can smell at conc. as low as 0.02ppm-0.2ppm dependent on the person. A general safe limit is 0.5ppm. So if you didn’t smell it your probably okay.

In case you don’t know the smell. Ozone has a clean refreshing smell at low levels (like air after a thunderstorm). At higher levels it’s very sharp and unpleasant and altogether ones of life’s run away from the badness moments.

If you search wrongdiagnosis.com for ozone you’ll find a story of the dangers of ozone.
