The sciatic nerve runs from the spine down the entire length of the leg into the heel:

and as pain can sometimes "telegraph" (pain felt at a location distant from the actual source), a problem in the spine can be felt anywhere/all along the nerve.
Sciatica can come from problems with discs, facet joints, and other sources.
Google:
facet joint sciatica
The diagnostic spinal block was just that -
diagnostic. It is used to help figure out the source of your pain.
The epidural injections are
therapeutic injections. In this case, aimed at reducing inflamation by use of steroids.
