Thankyou so much heavymetalme. I hate not using people's real names, stupid I know. Anyway as I said I thank you for giving me at least he chance to rule this out. Please thank your wife for me, as I said I know it's a shot in the dark, but as some of my family have had those same symptoms I have to know for sure I hav'nt got it so something could be done for my children. Thankyou so much love Tracy. xx
