10. Ringing or buzzing in the ear
Lastly, another very common sign of an ear infection is hearing a ringing or buzzing sound in the ear. The swelling within the middle ear could actually cause reverberations that affect the ear drum, which will result in hearing a buzzing of ringing sound.
The sound may be mild and hardly noticeable, or it can become intense and high-pitched. It might also wax and wane, meaning that it will be more pronounced at certain times of the day than others. See a doctor as soon as it’s possible to avoid long-term hearing problems.
