About a year ago, my jaw popped. It was like a joint popping, like your knuckles or fingers ... but hurt at the time. it was EXPLOSIVE. I popped it a couple of more times like that in the matter of a week or so ... and only succeeded in displacing the disc in my left TMJ. Yay. I recently rubbed those TMJ joints, trying to figure out what exactly was making the clicking sound (I didn't know much about TMJ at that time), and inflammed my TMJ joint. I spent the week trying to not open my mouth much and let my joints heal. Once my right TMJ joint (the one with the displaced disc) settled down, I was driving home from a movie and casually popped the LEFT TMJ. It wasn't an explosive pop, but was certainly a pop, and that joint was sore afterwards. That was last night. I'm currently terrified that I'm on the verge of displacing my left TMJ disc, and I'm wanting to know if anyone has any kind of information of trying to avoid disc displacement or popping of the jaw joint! Please help!
