An accurate cause or trigger for Tinnitus is not yet completely understood, and cases may emerge without any obvious explanation. The symptoms of Tinnitus can begin suddenly or gradually, and with or without any clear reason. However, it is known that Tinnitus may be associated with:
A current ear infection, cold, or injury may sometimes become a source for Tinnitus that may or may not be short-term. You may also find that major noise exposure, or ear syringing may trigger Tinnitus.
Stress can trigger your experience of Tinnitus, or result in your current Tinnitus becoming worse. Research has shown the link between depression and noise sensitivity. When you are under stress, low frequency noise may become irritating whether you are experiencing Tinnitus or not.
It is considered doubtful that stress may actually be a direct cause of Tinnitus, however research done in this area shows that there could be a link. Some sources of stress such as bereavement, illness, divorce, redundancy or major exams may at times be the trigger for Tinnitus, or worsen any pre-existing symptoms.
Nevertheless, Tinnitus can affect people in different ways. A few people discover having Tinnitus makes them feel stressed, anxious, tense, depressed, and lead to difficulty getting to sleep as well as staying sleeping. Anyone already suffering from depression may find symptoms become worse after developing Tinnitus. This can lead to a vicious circle where stress and anxiety can make Tinnitus worse, and then this will lead to greater feeling of anxiety and stress.
