Never gone through this myself, thank god, but I do/did work work with a guy who had to have this done, due to pretty bad back pain. Doctor said his recovery would be 3 months, and then light duty on the job (ER nurse), he did all the physical therapy and was pretty aggressive about it, but smart as well, and back at work with no limitations and zero pain after 2 months.
Don't know if this helps, as I'm pretty sure this guy doesn't lift since he works about 8 days a week. Maybe someone else on here can chime in?
