Doctors and Nurses are Notoriously known to be bad patients, it is simply " do as I say not as I do" situation! Especially if it is their first surgery or first back surgery, after the first time we learn from our mistakes or at least sometimes we do, LOL I have found for me, that while being in the hospital I am very very impatient, with nurses that do not do their job properly, but also wise enough to know that I have to repress some of my anxieties, because I also know that you don't want to make them to mad or upset with you or anything like that!!! Because like it or not there are ways that the nursing staff can make a patients life even more miserable, and sadly there are some individuals that would do just that!
Try to be patient with the patient David, and good luck to you!!!
