Tinnitus isn't a disease, it's a problem in which a person hears clicking, buzzing, swishing, or ringing on one or both ears. The condition can be caused by medications, tumors, ear trauma, exposure to loud noises, and Meniere's syndrome. The sounds coming from the ear can be so bothersome that it affects the person's quality of life.
In summary, the perception of a ringing in the ear in the absence of a sound is thought to result ultimately from the cortices of the brain spontaneously increasing their activity and is associated with changes in the organization of the auditory cortex. But many aspects of tinnitus remain mysterious.
