Hi and thanks for the query,
I guess you can fly.
Take a few precautions
Half an hour before flying instill decongestant nose drops like otrivin
into your nose. Instill 3 drops in each nostril
. Read the instructions on the crimp for instilling the drops.
Repeat the procedure half an hour before you land if the flight is longer than 5 hours.
You can chew gum and drink some liquids during take off and landing, it will help to equalise the pressure.
