I have hyper acoustics. I am 54 years old and have perfect hearing. Years ago my daughter was falling asleep behind me and each time she blinked, I heard the click associated with her blinks. Recent hearing test confirms no loss of hearing. Changes in the acoustics of work place made tolerating and processing sound impossible. Experienced fullness in head, disorientation, vertigo, headaches, rocking back and forth uncontrollable while standing when exposed to loud sound, sharp sound, high pitch sound. After I am removed from the noise, i.e., church, social functions my ears ache. I am unable to sing with the choir because of the sounds of the instruments. Sometimes experience a pulsing sensation in ear canal. In the early stages of condition I experience what felt like a cold sharp spike being shoved in my ear an an upward angle. Hearing shifts from right to left causing loss of balance and listlessness. To date I am not able to tolerate loud noise. I use professional ear plugs 25% noise reduction in noisy environments. Takes all the pleasure out of listening. Moisture accumulates in right ear from time to time. I m not crazy, my symptoms are real.
