<unk>  is self-limiting inner ear disorder, often secondary to viral infection. The infection of vestibular neuron and labyrinth primary affects balance and hearing. The condition is commonly called as vestibular neuritis/ vestibular neuronitis. It is basically an inflammatory process of the labyrinth, which is the inner ear, and contains the vestibular system. Thus, it is responsible for sensing the position of the head and body on the whole. It contains fluid-filled channels, which in turn control the balance of the body and hearing. With any movement, the fluid moves in the channels and transmits electrical signals to the brain, thus helping the body to balance. Due to the difference in the transmitted signals from the inflamed and noninflamed ear, derangements can occur, which ultimately makes the person feel dizzy .Along with balance problems, patients often experience hearing loss and tinnitus. Usually caused by a virus, or from bacterial infection,upper respiratory tract infection,<unk>  can also occur due to head injury, an allergy or as adverse drug reaction to any medicine. Although rare, all these can cause permanent hearing loss.<unk>  is also known as Vestibular neuritis or acute peripheral vestibulopathy . Mostly, it is a self-limited disorder, with acute short term symptoms like vertigo, nausea, vomiting, and gait impairment, with complete recovery in most patients. Another common condition associated with<unk>  is anxiety, which produces tremors, palpitations, panic attacks, and depression. in many cases, panic attacks and anxiety are the first symptoms to be associated with<unk> .
