It is probably too soon for a biopsy.
If the dorsal roots are causing the pain (like from viruses), the biopsy would not show damage for quite a while. Long term damage from the dorsal roots along the spine, will cause atrophy in the periphery.(this has been shown in animals so far).
The explanation is in our dorsal root thread in the subforum.

This is a collection of diagrams of the dorsal roots from Google images:
