7. Headache
A migraine may be caused by stress, pollution or exposure to loud sounds. These headaches can also be caused by ear infections, or an irregular air pressure in the ear.
This pressure can be felt in the tubes and the head. It is a temporary effect of high-altitude sports or flying in an aircraft.
If you have a headache that is accompanied by ear pain and has been present for a long time, it may be due to an ear infection.
