Your : Your explanation sounds like you may have "trismus", which is an inflammation of the muscles you use to chew. Have yourself evaluated by your dentist or an oral surgeon for the proper diagnosis and treatment.

Lock: If just occurred with no reason, it might be from your tmj. The disc slipped forward and can not go back. ("closed lock"). Myofascial pain and infection (serious issue) can cause the same problem.

Spasm or TMJ: This can be caused by spasms of the muscles that control the closing of your jaw or a problem with the articular disc(s) your jaw joint(s) commonly referred to as the tmj. In the meantime you can take some otc medication such as advil, Motrin or aleve (naproxen) and some warm compresses to the outside of your face just in front of your ears. See a dentist as soon as possible for an evaluation.
