My tinnitus is only 2 weeks old, and I went into overdrive finding a cure or a solution, because I read that speed is the primary differentiator for success or not. I tried a lot of stuff and some helped a bit, but: I actually just came back from physical therapy where my jaw muscles get massaged inside and out. There was an immediate tinnitus relief, like 80%. Look up TMD (Temporomandibular joint dysfunction). Ibuprofen helped, too.
