How a jab in your ear could banish tinnitus for good

An injection that's administered into the eardrum could help relieve tinnitus, the Daily Mail reports.
The jab contains a drug that blocks the brain chemical glutamate, which is thought to play a key role in the development of tinnitus.
Laboratory research showed that a single dose of the drug cured tinnitus in people with noise-induced hearing loss.
Tinnitus is the term for unexplained noise in the ear, such as a high-pitched whistling, ringing or hissing. The noise might be constant, or come and go over time. A third of us are expected to experience the condition at some stage.
There is no cure, but the new treatment appears to be an effective therapy for noise-induced tinnitus.
The drug, named AM-101, focuses on the fact that hearing problems such as tinnitus are linked to excessive amounts of glutamate.
