Almost universally, epidural steroid injections (ESI) contain a numbing agent like lidocaine. This anesthetic allows a diagnostic component as structures will be “numbed”. The ESI is a variation of Transforaminal ESIs and Selective Nerve Root Blocks (SNRB), which are more precise. The goal of the ESI depends upon why it is being used. See:
