Sorry to hear about your problems with your back.It seems most men have some trouble, some time in there life with their back. I too know something about your problem,as I have had 5 back surgeries,I can't fish for long periods of time ,but I still go when I can. I have a place on Barkley Lake,and after my last surgery.had given some thought about selling my place.But I decided that it is what I love to do most,and will fish as long as I can.
I go out and fish sometimes for 3 or 4 hours,until i can't enjoy myself for the pain,and then I go back to my place,for the rest of the day. Sometimes I will have to skip a day or two,and sometimes not.I just fish when I can.
Hope you heal up well,and don't give up even if you still have a few problems with it ,Where there's a will there's a way.
