I just had a lamenectomy, and single level fusion of L5 S1. So far so good. I recieved a Biomet Spinal Pak II bone fusion stimulator yesterday and am using it as I type. My surgery was just 3 weeks ago, and so far it has produced great results thank god. My concern currently, is that my doctor told me that I could return to work after 12 weeks post op. I work for UPS, so I have a physical job that involves bending, twisting, heavy lifting, and often lots of steps. If anyone has any experience with returning to a physical job, I'd love to hear them good bad or ugly.
