Joseph, Oh, it's always a weekend and such a heavy worry. Rod had something show up in his chest xray prior to surgery, had another scan and it turned out to be some old scarring probably due to some infection in his teens! We are hoping the same for you! The bone scan can show any old injury, in our case softball in the shoulder and "home improvement" injury to the knee! So, most people expect something! Hang in there, we'll be thinking of you!
