I suppose mine is not uncommon (see below) but I have noticed it again of late and cannot deny the connection to excessively stressful events in my life.
I involuntarily keep my jaw clinched and within a day or so I get a piercing pain in my jaw up by my ear. Anyone have a cure for this? I've even tried a rubber mouth piece but it doesn't stop the clenching. Vodka and xanax seems to help.
