About a year ago I had my jaw lock, which was terrifying for me because I have a huge fear of dislocated joints and was convinced I had done it to my jaw. Ever since then, I have been popping my jaw all day, every day, every 20-30 seconds for fear that, if I did not, my jaw would lock again. It makes a clicking sound and, although it doesn't hurt, I am afraid that I am injuring it. Does anyone else have this problem or any other sort of "tick" they can't stop no matter how hard they try?
