In fact some statistics claim as many as 1 out of 5 people in the U.S. have tinnitus at some level.
Although tinnitus is not a disease because it is a symptom of greater health problems, but a person with tinnitus may have problems with balance and experience mild to severe headache, dizziness, pain in the ear, etc.
