Hi,
Thank you for posting your query.
I have noted the findings of your 
MRI lumbo-sacral spine. To give you proper advice regarding treatment, we need to know the clinical details. 
At this stage, you need 
physiotherapy, mainly the back extension exercises.
If you have 
back pain or leg pain, then, 
pregabalin or 
gabapentin capsules would be helpful.
I hope my reply has helped you.
I would be pleased to answer, if you have any follow up queries or if you require any further information.     
Best wishes,
