<unk>  preferentially affects the apex of the<unk> where low-frequency sounds are interpreted. Due to the fluid imbalance in this area, parts of the<unk> are stretched or under more tension than usual, which can lead to distortions of sound, changes in pitch perception, or hearing loss, all usually in the low frequencies. Common symptoms include: * Low-frequency sensorineural hearing loss. * A feeling of fullness in the ear. * Tinnitus (ringing in the ear). * Diplacusis (the perception of sound being a different pitch in one ear). * Hyperacusis (an intolerance to loud sounds). * Depression or anxiety that the condition will worsen or progress to Meniere's disease. As with Meniere's disease, atypical, early, or mild cases may only present some symptoms.
