Dad update - he is very very very tired, every movement makes him breathless, he has lost a lot of weight and just can't be bothered - not eating very much (did manage to get the ice cream down - typical eh) and everything is too much effort. Having said that I personally don't think he has quite given up yet, they have put some dye round him and done another scan today to see what is causing the pain in his lower back, in the back of our minds is secondaries but nobody has said it to him. Should have results in a few days they have said. Just wish it wasn't a 70 mile round trip - will go again at the weekend. Thanks for thinking of me you guys xxxx
