I used to have a hearing aid (for 8 years) because one of my ears is only doing half of what it should. I remember that I had a headache the first week I started using the hearing aid, so many sounds!

The sounds never stopped bothering me were cutlery on plates (especially when eating in a restaurant), newspapers being turned over and people whistling. Argh.
My hearing aid has been living in a drawer for the last 5 or so years now. For me it simply wasn't worth the trouble of cleaning it, getting new batteries, and putting up with the above mentioned sounds.
One thing that really bothered me about getting a hearing aid, was the woman who fitted it. She kept telling me to grow my hair so that I could cover the hearing aid up. I was totally okay with it being visible (glasses are visible too, so why hide a hearing aid?), and then she tries to make me feel ashamed? Sheesh!
