For the last couple of weeks I've been suffering from pain, and a clicking sensation, in my jaw whenever I yawn or open my mouth wide.
Having looked it up on the net, my best guess is that I've managed to somehow injure it when I did the Helsby half last week. I hold my jaw pretty tense as I run - the harder the run the tenser it gets, and this seems to be the most likely cause.
Has anybody else had this problem? Its not dehabilitating, but its slightly alarming seeing as every time I yawn I worry my jaw is going to lock. The internet suggests applying a hot water bottle - does anybody have any other suggestions?
