Trixit - I have multiple symptoms. My jaw clicks and pops terribly, facial pain and numbness, headaches (migraine type, tension and sinus). Earaches, neck and shoulder pain..... depression. I go in for an adjustment to the appliance on thursday.
The swelling around my jaw joints has been reduced, my headaches are definitely getting better. Everything seems to be improving at this point. I've had the appliance (night guard) for about a month now.
