I kind of know what this is like. I've been deaf since I was about 2.5 years old. I'm nearing 23 years old now.
A few years ago I was in London for my Consultant's appointment. My consultant notice some wax in my ear and asked a nurse to wash it out with water. This involves squirting ice cold water into your ear, presumably at pressure, to get dislodge the wax which then is meant to flow out of my ear and into a cold (and I mean freezing cold) metal bucket. This bucket is so cold when pressed against my head I feel ill.
Anyways nurse turns the water on and instantly MASSIVE pain in my ear. Nurse gets consultant. Consultant checks my ear out and sees a perforated eardrum. She tells the nurse to do the other ear instead.
Get home and the next day I have black gunk pouring out of the ear with the perforated ear drum. Yayness, can't wear hearing aid; can't go to school.
And to complete the set I had green gunk pouring out of the other ear which means no hearing aid in that ear either and no hearing until gunk sods off.
So all in all I love getting letters for appointments with my consultant.
