I am extremely sensitive to sound. All sounds can appear to be too loud yet in a tunnel at times. Reverberation seems to be what happens in my ears. Sometimes I have problems with left ear and all the time with right. I can muffle the sound and hear better most of the time. Or I can create a tunnel than it is uncomfortably loud. I am wondering if it is nerve damage or the cartiledge in my ears is closing and yet I cannot tolerate at times all sound. I seem to have a white noise going on all the time..sometimes lesser than other times.
