most of the time. unless you are in a lot of pain or have an active infection you will be fine. but. there are many variables including the speed of take-off and landings airports etc. that can affect your eustachian tube's ability to equalize pressure. there are a few things you can do: 1. try a decongestant like sudafed before your flight or use a short-acting nasal decongestants. 2. ibuprofen can help too as an anti-inflammatory. 3. chew gum but really what you need to do is swallow (sips of water saliva etc. ). if you feel pressure try yawning.
is it okay to fly after having an ear infection that has cleared up even if my hearing has not returned to normal?
