The results of the nerve block help to indicate that all your symptoms stem from the nerve root. You could have a hematoma (pooling of blood products) that can cause compression but this can be ruled out based upon a new MRI with gadolinium.
The “debris” is unlikely to be scar only 2.3 weeks post surgery. This debris is most likely a recurrent herniated disc or some fragments that could have been “hidden” when the microdiscectomy was initially performed.
Please let the forum know how you progress.
