Use background noise to forget about tinnitus. You could leave your TV or radio on, or even hum and sing yourself. Covering the ringing noise will quickly become a habit, and you will soon not even think about tinnitus anymore and simply drown it in other noises. You should be careful about the volume of your background noise.
If you are diagnosed with tinnitus and told that it's both incurable and that you'll be afflicted with it for life, get a second opinion. Tinnitus is not life-threatening and there are various treatments which can offer you relief or even a cure. So take heart, and remember, there is always hope!
Having a good team of medical professionals is key in treating tinnitus. Talk to your physician about whether or not you should schedule a visit with a specialist in your community, and if the answer is yes, get a referral from them as quickly as you can.
