Hi all, i also suffer the same. dizziness at different times of the day. not spinning vertigo, but more giddiness and a feeling that you arent quite with it. I also have neck ache and tension. Just like *D* i dont realise im doing it but all of sudden i realise i have my teeth clenched and shoulders shrugged. then i let go and within 10 minutes i realise im doing it again. this leads to jaw ache, neck ache, shoulder ache... i have been suffering anxiety and am getting over the nasty thoughts and psicological side of things, but dont seem to able to get rid of the physical side of things yet. i suppose it comes with time. went back to tennis this week after 7 months out, and now i ache cos im out of shape!!! but feeling more tired helps relax. take care all.
