Hi Peterspots, when I went through a few months of meno misery a few years ago - insomnia, joint pains, anxiety etc.....I was left with dreadful facial pain from jaw clenching and teeth grinding. In fact, this sounds quite ridiculous now, one day I took myself off to A&E and told them I had rabies (I had been googling and it is one of the symptoms). I saw a physio who confirmed that I was grinding my teeth. It did go as I slowly relaxed more but it did take a while, have you tried relaxation tapes etc. your body is still on red-alert!
