L5 is sacralised.
To be on the safe side my doctor suggested waiting to see my surgeon in October for the 8 month follow-up consulation before returning to work. However, I can do most things. Do posters feel that this is good advice - I feel a bit of a fraud after 7 months? At the moment I am not earning.
I did wonder if maybe L5 and S1 should be fused as well.
