What is the gold standard for local anesthetics that reduces the pain significantly of a disc herniation?

Targeted nerve blocks that use a local anesthetic to pause pain transmission from a specific pain generator are most informative here. The medial branches of the dorsal primary rami supply the facet joints, and blocking these nerves with a local anesthetic can produce rapid, significant relief if facet-related pain is contributing to the disc pathology. This approach serves both diagnostic and therapeutic purposes: a strong, short-term reduction in pain confirms facet involvement and provides meaningful relief, and it can lead to longer-term strategies like ablation if the response is robust. Epidural injections rely partly on anti-inflammatory steroids for longer-term relief and are not a pure local anesthetic block, so they’re not the same kind of targeted, immediate analgesia. Intrathecal morphine delivers opioid analgesia with a different risk profile, not a local anesthetic nerve block. Subcutaneous lidocaine lacks depth to affect deep structures like facet joints and the disc complex, making it less effective for disc-related pain.
