dear fiona i got exactly the same crap from the doctors as you in fact read my post on doctor manager i now have all my amalgams removed feeling bad but i have an alternative health woman who helps me and she is good ive also booked in with another dentist in london to check i dont have a cavitation and there is also a neurologist there im going to see who worked for the nhs FOR 20 years then got fed up with their crap the best test i have used is a test you can find under osumex on the internet but i also had a test last year at a private hospital in london called the Breakespeare if you go for vega test find someone very good cos i had different results from mine so thought they wernt that reliable my natural health lady told me i had mercury poisoning before i told her anything she works for Acmos i dont think id be coping at all without her support good luck Tracy
