Update:
Cliff spoke with surgeons and when they spelled it out for him, he (rather quickly) opted for them to amputate his leg. Surgery is tomorrow.
They told him that he would never be able to walk normally and that he would be dragging "that thing" behind him for the rest of his life. Furthermore, they told him that it has already almost killed him twice already and he would continue to be subject to possible blood clots.
What made him settle on his decision was also when they told him he would need further surgeries every few days for the next 3+ weeks...cleaning it...staving off infections, etc.. Cliff said he's been through a virtual hell and cannot stand the pain and suffering any longer.
We're all perversely happy about his decision, as it's been a terrible stress on his wife and brother, who've spent virtually all their time at the hospital, even sleeping there. Everybody needs to get on with life.
We also know it's going to be a long haul for him...getting off the pain killers and other drug cocktails necessary to keep him sedated, and also the physical therapy.
He's a strong man. We're all very proud of him for reconciling the situation so quickly.
Once more, thank you everyone for the prayers and well wishes and for allowing me to share this ordeal with you all.
