I really don't know what to help you with ringing in your ears. my husband is almost deaf now due to that. It would drive me crazy. instead his having the t.v. as loud as he can is doing that.
TMJ is helped by wearing a mouth guard. You don't even know most times when you are grinding your teeth or clenching your jaws. so you must get one. My insurance paid for some of the cost of mine. it cost about $400.00 but they may have cheaper options.
good luck hon.
