I have very loud hissing T in my left ear. My hearing loss is so bad my hearing aid specialist told my I could not help it if I got a hearing aid for my left. After one week with T, I made an appointment at Costco and purchased a left hearing aid to match my Rt one. The brand is Rexton. They were not cheap because Costco doesn't take insurance. $2300. for both. They give you a 6 months trial and a 3 year guarantee. It's my 3rd week and I can see light at the end of this hell. I can totally mask the T with them. But I keep the volumn low enough to here the T so I can eventually get used to it without the hearing aids. When I sleep at night I use a white noise machine and wear my right aid only. I can here the noise maker and sleep all night. I also take an Ambien 10 mg. I have been taking it for years. It takes me a little while to get going in the morning. But I feel good. I have gotten back my senses and my appetite. I can beat this and you can too. Don't stop trying. I've got Arthritus so bad I've had both knees and both shoulders completely replaced. I've had a heart stint and need back injections every 4-5 months for pain. This T is a big challenge. It can be so depressing but you can beat it. Hearing aids and a noise maker are my best friends now.
