Can you fly with otitis externa?

See below: You may be okay as long as you don't have inner ear (otitis media) involvement with the otitis externa or fluid behind your tympanic membrane. If you do that would be very painful on the flight.

Usually you can: Otitis externa only involves the outer ear, and this part of the ear is not sensitive to pressure changes. If the infection involves the ear drum as well or behind the ear drum (with fluid or negative pressure present- your doctor or ENT could tell you), then flying can be painful. I would get checked before the flight to be sure what is going on.

Probably: Depends on severity. Need to check with your treating physician.
