My left ear is ringing right now, as I type this. I have had tinnitus in my left ear for several years now, and the best treatment is to accept that it's there. Otherwise, it can be crazymaking.
Like the doctor posted earlier in this string-- go to an audiologist-- please. You didn't specify if you have tinnitus in both ears, or just one. But, a hearing test will reveal a lot, and will give your ENT doc info about your condition-- as he did with mine. Much like everything else in the "practice of medicine" a lot of this testing is done to rule things out. In my case, my hearing test caused the need for a CT brain scan, but it came back with no issues in my brain or ear canal. That's important because nodes can grow on your inner ear nerves, and the can be benign or malignant-- and they generally have to take a part of your skull out to get to the nerve. So, it's a lot like brain surgery-- as in serious.
Meanwhile, I listen to CJ tube amps and a CJ tube preamp and an Oppo 105D with Modwright (several tubes) through Egglestonworks speakers. This combination nearly always makes me either forget that I have tinnitus, or actually makes the ringing go away-- which makes me listen to music for several hours at a time on a regular basis.
Hope this helps.
