Tinnitus started 4 weeks after my mTBI. Depending on other symptoms level dizziness, fatigue etc., it gets louder. Tinnitus is something has no known cure.

I talked to some one who had terrible ringing and he tried several things Xanax, Hyperbaric Oxygen Therapy, Neuro Cranial Restructuring (NCR) and TMJ appliance and finally said he is free of Tinnitus. Now he uses the TMJ appliance only when he sleeps and he says that is the life saver.

Other methods helped too he claims especially NCR and HBT. All these efforts took few years and lots and lots of time and money and traveling to different places to get treatment.
