I need some advice. im told I need a fusion on L4 L5 S1 with hardware next month. ive had prior back ops the most recent was 2 yrs ago, but no fusion was needed then. reinjured my back at work. I work in "the public eye" & deal with the kind of people most don't want to deal with. im worried that I may have to take a medical retirement, which I don't want to do. I have 10 yrs to work before I can "retire" retire. hobbys I don't want to give up are mma training & drumming. will I be able to do any of these after this surgery?
