What Is Tinnitus?
Noise that seems to be coming from inside your head is called tinnitus. Tinnitus symptoms can be temporary or permanent and can be rooted in a wide range causes. The most common causes of tinnitus are loss of hearing, drugs or medication, or prolonged or acute exposure to loud noises. Tinnitus is not a disease. Rather, it is a symptom of an underlying condition. The majority of Americans will experience tinnitus many times over the course of their lives.
Hearing Loss: Damage to the cochlea caused by aging, trauma or certain drugs can result in tinnitus symptoms. The theory for why this happens is based on how the brain handles the eye's blind spot. With the eye, the brain fills in the blind spot in our vision field to make it the same as the surrounding color field. It is theorized cochlea damage produces gaps in normal signaling which the brain fills in, creating tinnitus symptoms.
Exposure to loud sounds is a frequent cause of temporary tinnitus. Examples of when this might occur are; after attending a music concert; after watching an action movie in a theatre where the volume exceeded recommended levels; after using power tools in an enclosed space. The most commonly reported tinnitus symptom in these cases is a ringing in the ears. Prolonged exposure to a noisy environment without ear protection can result in permanent hearing damage and chronic tinnitus (see below).
Medication: Overuse of common aspirin, also called ASA or acetylsalicylic acid, can cause tinnitus symptoms, as can the anti-malarial drug quinine and antibiotics that include aminoglycoside.
Tinnitus symptoms that are reported by some sufferers in addition to ringing are buzzing, a high pitched humming, roaring or whooshing, hissing, clicking, whistling and sounds like waves crashing.
Misalignments of the jaw and muscle spasms in the ear or throat haves been cited as causes of the tinnitus symptom of clicking. Ear sounds that follow the pulse of the individual's heart are called "pulsatile tinnitus" and are caused by blood flow in the blood vessels of the middle or inner ear. Pulsatile tinnitus can be a symptom of thyroid problems. Other conditions associated with pulsatile tinnitus are pregnancy and high blood pressure.
In rare cases tinnitus symptoms are caused by tumors. A tumor that presses on the ear's blood vessels will cause pulsatile tinnitus. A tumor on the nerve that carries the signals from the ear to the brain's acoustic processing center creates a condition known as acoustic neuroma. Unlike common tinnitus, this condition occurs in only one ear. For this reason single ear tinnitus should be investigated immediately. - 17273
