I've been suffering from severe low back pain and sciatica for over 8 months now, have had to microdiscectomy surgeries with a laminectomy during the second surgery and am still in pain. My surgeon says theres not much disc left at l5s1 and there is alot of pressure at l4l5. His PA says an l5s1 fusion would help, but I may want to consider getting the fusion from l4-s1. Has anybody had this fusion done before? If so, what are the limitations after the full recovery? The reason I ask is because I have a physically demanding, fast paced occupation and am wondering if I will be able to return. Any advice would help for I have until February to think it over. Thanks.
