I can see why there's health condition frustration and it's a complicated environmental and economic situation. Most with tinnitus don't have bothersome issues. For the ones that do, then this is where the debates begin with the complex issues surrounding available treatments as seen on talk message boards. Many of us have posted valuable links of highly professional research with treatment options, but it appears that many don't bother to read. My guess would be that the average improvement rate for all treatments of moderate/severe tinnitus is beyond 20%. That's for both noise induced and physical cause. As to where to get many of these treatments is blowing in the wind.
One frustration is that treatment for tinnitus can at times be a catch 22. Vitamin C can help both with noise induced hearing loss and physical tinnitus as oxygen and circulation therapy matters. For a few, even a high intake of Vitamin C could cause other problems such as stones. The number one negative for those with neck tinnitus is heavy headgear or noise blocking headphones.
The Cleveland Clinic does studies and treatment for those with facial tinnitus trauma related to neck, jaw, TMJ/D and nerve imbalance with great success. For a fact, I know that the 2 largest hospital associations in my area for ENT consultation average 25 minutes. Most ENTs do not have the knowledge or time to go beyond standard treatment. There's an ENT site that anyone can visit, but it's hard to post unless you are a medical student or doctor. There's hundreds of topic conversations where ENTs ask each other dumb stupid questions that include how to treat those with tinnitus. And that famous phrase is often mentioned, but they do discuss often how much money they make and that's expressed as fast patient turnover. Some professional articles state that 50% can see at least a 25 percent tinnitus deduction with proper healthcare treatment.
