Tinnitus is a lingering symptom that results in ringing, buzzing, roaring, clicking, whistling or hissing in the ears even though there isnt an external presence of sound, according to the Mayo Clinic. And close to one in five Americans suffer from the symptoms. This condition could be caused by an ear infection, wax build-up in the ear, nasal allergies, certain medications or exposure to loud noises. More rare cases of tinnitus have been linked to head and neck tumors, high blood pressure, cardiovascular disease or poor circulation. Solutions to help relieve the ringing in your ears include acupuncture, hypnosis, ginkgo biloba and zinc.
