I went through that. Take it slow. I cut out of work early and increased my day at work by 15 minutes each day until I got up to 8 hours. I also had trouble walking as I could only take short steps. I started walking downhill to lengthen my stride. That was 20 some years ago and I am dong fine. You will figure out what is best for your recovery and you will know when you have done too much. I couldn't stand to do nothing so I carved a duck decoy out of foam. It was too painful to use wood. I made a plaster mould out of the decoy and used that to make more foam decoys. I still use them in my sets when duck hunting. I wanted to have something to show for my time. I know what I would do in your situation, I would get one of my bikes and polish the chrome and wax it. Do a little each day. The movement is therapy if you don't over do it. No lifting it though. I also do a half hour of stretching each day and that works magic for your back.
