I would guess you have TMJ. I have had this condition for MANY years, never knowing that it was a classic Lyme symptom. I have all of the above, pain , ringing and my jaw actually drops back. If you look at your mouth sideways in a mirror your bottom jaw is normally pulled back with TMJ. I wore an appliance for years but I do believe I got little relief because the lyme was causing it all. Do you hear a loud click if you move your bottom jaw back and forth? D
