The reason I can't have more surgery is because I have no original bone left therefore there is nothing to attach the prosthesis on to. My Dr is Mr O Toole, he practices in Dublin and I must say I have the upmost respect for him. He is an extremely talented man and has always had my best interest at heart. I think it's just a case of me slightly unlucky. I had a bone tumour in my pelvis when I was 17, since then I have had numerous things go wrong. People tend to think that cancer is terrible but in my case the cancer was a breeze compared to what came after. But it's on message boards like this that I find new ways to tackle my ongoing ailment so thank you for your comments, and if you have any more advice or coping mechinisims feel free to send them my way!
thanks again guys.
