What causes tinnitus?

Tinnitus has many related triggers, and they can differ from person to person.  Ear-related triggers can include but are not limited to, hearing loss or changes in hearing, infections of the ear, wax blockages in the ear, barotrauma, or excessive noise exposure. Whilst non-ear related triggers such as whiplash injuries, muscle tension, jaw pain and stress can also contribute to tinnitus development.
