Clicking IDK but the jaw pain is most likely as people have said from grinding your teeth.

I personally clench and grind very hard when I sleep. Apparently in you sleep you can clench your teeth an amazing amount causing long term damage. You can usually tell if you are grinding because your teeth will wear down gradually or your front side teeth will become kind of pointed.

If you've been having this for 3 years I would imagine that's causing the clicking too... from long term jaw deformation.



Walmart sells nightgaurds which is like a mouth guard that are like $30. Kind of a lot of money but having your jaw reconstructed would be lots $$!

Give the mouth guard a try. If it still bothers you or is that bad go see a dentist.
