hang in there Dad. Don't be sad. Your doing the right thing asking questions. Get the right diagnois.
when i went to give blood for my mom they called in a doctor at the hospital to find out whether i should give blood or not. He couldn't recommend or not but he told me the same thing. Plastic surgery and grafting. I was like " uh huh " Ask could i come back and see his superior when he came back from holiday. yeah right.
