We finally got results of CT scan that their is nothing showing up as a problems re aneurism so the appt. for stem cells is scheduled. As you all can imagine it was a relief to know he wouldn't be facing a surgery at some point in the near future. Anyway, he's reading the book and looking forward to feeling better. Ever since his fall and even though his ribs are pretty much recovered, he can't walk very far even with oxy. And he doesn't feel very well most of the time but there's nothing else wrong. His saturation is often high 90's with oxybut it doesn't matter. Is this typical? I've urged him to go back to exercise at the hospital pulmonary dept. and I think he will do that this week. Thanx all for support. Regine Wilson
