Ask for a copy of ur report and self educate yourself on what it means.
My suggestions:
1. Is surgery necessary?
2. Non-surgical options?
3. Activities/exercises that will not aggreviate your lower back
4. Pain management/medication(s)?
5. Referral to a Spine Specialist/Orthopedic Specialist/Neurosurgeon?
You don't know the results yet, so it is kinda difficult to recommend what to ask
your primary physician.
Keep us posted.
