Since flying back from South America in March, I have had recurrent low level earache in both ears. The discomfort is enough to make me take ibuprofen each evening, when the ache seems to be worse.
Warm olive oil does help but the ache comes back again.
Do I have an ear infection, or will it settle down eventually.?
It sounds as though you have blocked Eustachian tubes asa result of your flight. Pop to the chemists and get a Vicks nasal Spray or Otrovine nasal spray and spray into your nose every four hours.
It is extremely unlikely to be an infection.
