I've been hearing a buzzing sound in my ears. What could be causing it?

You may be experiencing tinnitus, which is the perception of noise or ringing in your ears. Tinnitus can be caused by many things including stress, loud noises, ear infections, and medications. It can also be a symptom of hearing loss. If you are having trouble sleeping due to tinnitus, try using white noise machines or other relaxation techniques like meditation.
