hi mark. you sound like just like me. abit scary i thought it was me who written it. had two check twice. <img src="/ubbthreads/images/graemlins/smirk.gif" alt="" />

i too have numbness. ive had a brain mri,ct scan,loads of blood work.and they cant find anything wrong.apart from having hypotyroidism. which i know can mimic ms.
all my symptoms came on about 4 years after having these bloody fillings put in my mouth.
i had my fillings removed about 6 months ago.and i am starting to feel better. your problem is most likely the fillings.
but have you considered checking for lyme disease.
i was tested referred to a specialist,to see dr owen in cardiff. who sends your blood work to igenex in america..
maybe worth looking in too...
