Ringing in Ears (Tinnitus) is the medical symptom of awareness of sound in the human ear or head when there is no outside source of the sounds.
It is not a sickness but a symptom of an underlying disorder.
Tinnitus is often called ringing in the ears but it may also sound like blowing, humming, roaring, buzzing, hissing, whistling, or sizzling.
The sounds the patient hears can be soft or noisy.
The patient may even believe he or she is hearing air escaping, water running, the inside of a seashell, or musical notes.
Nearly every body notices a mild form of tinnitus once in a while that only lasts a few minutes.
Constant or returning tinnitus is upsetting and makes it difficult to focus or sleep.
Almost 12 % of men who are 65 to 74 years of age are affected by tinnitus.

It is not known precisely what induces a person to "hear" sounds with no external source of the noise.
Tinnitus may happen with hearing loss.
Occasionally, it is an indication of high blood pressure, an allergy, or anemia.
Infrequently, tinnitus is a sign of a severe disorder like a tumor or aneurysm.
The causes of Ringing in Ears (Tinnitus) are:
Hearing loss is the most frequent cause.
Age or trauma to the ear (through noise, drugs, or chemicals) induce the injury of the segment of the ear for hearing (the cochlea) becomes destroyed.
Hearing loss can happen from loud noises
Because the cochlea does not transmit the normal signals to the brain, the brain becomes perplexed and basically produces its own sound (the tinnitus) to make up for the lack of normal sound signals.
Ear damage is normally noticed in both ears because both ears are normally exposed
The bad effects of extremely loud noise from firearms, high intensity music or other sources are a very frequent cause of tinnitus because of hearing nerve injury.
Ear infections or excess wax in the ear
Foreign objects in the ear can produce the ringing sound.
Drugs such as aspirin (if overused), amino glycoside antibiotics and quinine may injure the hearing nerve.
Alcohol, caffeine, antibiotics, aspirin, or other drugs can also induce ear noises.
Brain tumor called an acoustic neuroma which develops on the nerve that supplies hearing can induce tinnitus.
Meniere's disease -- an inner ear disorder that affects hearing loss and dizziness
his tinnitus normally affects one ear unlike the hearing loss in both ears.
The sound that they recognize in the ear or head has been mentioned as:
Ringing in Ears (Tinnitus) is diagnosed:

The most frequent treatments are:
There may be physical injury to the inner ear or ear drum, in which case surgery may be essential.
If no physical injury is discovered, the doctor will give different drugs.
Some doctors assert to be able to decrease the ringing by combining an inner-ear injection of lignocaine.
Vagal nerve stimulation in the patient produced a decrease in tinnitus lasting for 2 mths
