Tank, you do have a lot on your plate! I got through my 2d surgery (6 years after the first) as well or better than the first time, and I'm 68. One of my neighbors is a cardiac surgical nurse. She said I would see improvements in patient handling even in that short a time. I'm not sure how long ago your first surgery was, so I'll offer some maybe unneeded advice: Speak up to everyone in the hospital about your back issues and get the extra assistance you may need. Don't assume anyone already knows just because you've answered questions multiple times. They are well-intentioned, but (my experience anyway) is that the patient load is big, and they are dealing with the 'standard' patient of necessity. I'll be away from internet access until the day after your surgery, so I'll be looking for your successful report soon after my return. Best wishes for a successful surgery and a smooth recovery.
