My dad had a minor lower back fusion done years ago when it got to where he could hardly move without getting zapped. They have you up and walking around right away, which seemed both weird and slightly scary at the time. It took him awhile to find the 'right;' doctor as well. Some either act like they don't really want the job, or as if they don't know how to fix it so they error on the safe side and push you down to the next guy. I think they are shopping for easy money patients just as much as the patients are shopping them to be honest. Really annoying. Another relative has a bad lower back issue that needs fixed and has been here and there with different types of scans and multiple visits to specialists and is still looking for the patient/doctor match-up.
