There are many causes of tinnitus. These include noise exposure, injury to the head and/or neck, blood pressure and circulation problems, side effects of medications and, in some cases, allergies.
However, sometimes tinnitus can be managed by treating the underlying cause or by altering reactions to it. It is important to note that treatment outcomes vary depending on the specific cause of tinnitus, how long a patient has had tinnitus and other competing health factors.
