Can a nerve block cause permanent damage?

Rare: Though the esi injections are quite safe in the general parlance, yet there always remain some adverse reactions of epidural steroid injections. Temporary pain may be felt by a patient administered with an esi injection. There may be risks of spinal punctures, infections, bleeding inside epidural area with damage to nerves, headaches, & retention of water in the body.

Possible/unlikely: As a foot specialist, i perform thousands of injections a year in the form of nerve blocks for procedures and therapeutic injections. It is extremely rare to have any complaints of nerve irritation from the injection after the anesthetic wears off. Dr l.
