I have been nursing all my life....21 years as a CNA,,EMT for 27 years, and now a nurse for 13 years. I have constant back pain, siaticpain, and am not sure if my knees are gonna hold out....virtually falling apart at the seams.
But I would not change one minute of my nursing for sitting behind a desk or working in a factory.
You have to protect your back at all costs,,lift correctly,,bend your knees, don't lift with your back,,wear a back belt if you need it. Also, warm up before you start work,,,do some stretching,,,and most of all get help with lifting even if you are the slightest bit hesitant about doing anything by yourself
