I had TMJ, and still feel symptoms (an ache or slight stiffness) when I get stressed and grind my teeth at night though that is now rare. Self-massage did nothing for me, and my TMJ was bad enough that my jaw would be lock out of place for the first two hours or so after waking up. Sometimes, it would lock painfully while I was speaking, going in for a bite of food. All sorts of things. I never found anything that helped until one day I took a bite out of a burger, my jaw locked but my muscles I guess were too strong by then, I felt a ripping and my jaw snapped back in place, no more clicking, no more pain… I dunno what happened. And I’m kinda okay with being ignorant on that one. But like I said, the self-massage didn’t work for me, sipping warm tea helped loosen things up and help the ache when that was a problem. I’ve heard massage only helps some people. I’d give it a try.
