Thanks for the replies I guess we will just have to wait and see, I am just nervous because my dad really thinks they will do something and so far the specialists havent been much help, and I am worried he will get depressed if they are just wasting his time, but who knows!! my dad is going to Adelaide, the funny thing is he is thinking of moving over there for good and wants me and my family to go too, so we would all be together, its hard having a sister so far away, she really worries about my dad too, we are looking into the possibility of this. Also the two times my dad has been out to Australia his legs have improved I think the heat is good for him I know this is not the case for everyone.
