Our sense of balance is primarily controlled by a maze-like structure in our inner ear called the labyrinth, which is made of bone and soft tissue
At one end of the labyrinth is an intricate system of loops and pouches called the semicircular canals and the otolithic organs, which help us maintain our balance
is an infection or inflammation of the inner ear that causes dizziness
and loss of balance.
It frequently is associated with an upper respiratory infection
such as the flu.
infection or inflammation of the inner ear may cause above symptoms which you have describe.
Allegra contains fexofenadine
which is a antihistamine and it reduce the inflammation of the inner ear.then you may feel much better.So this is my explanation and it could be labyrinthitis.
