Millions of people in the United States Have tinnitus. People with severe tinnitus may have trouble hearing, working or even sleeping. Causes of tinnitus include hearing loss, exposure to loud noises or medicines you may be taking for a different problem. Tinnitus may also be a symptom of other health problems, such as allergies, high or low blood pressure, tumors and problems in the heart, blood vessels, jaw and neck. Treatment depends on the cause.
