Usually the eustachian tube drains fluids out of the middle ear through the back of the throat. Sometimes a cold, allergy or sore throat can cause the eustachian tube to swell up and shut. Tonsillitis and sinus infections also result in earache, especially among children. Sometimes high altitudes or rapid change in altitude, as when flying, can cause earache.
