Understanding Nerve Block Injection
A nerve block injection delivers medication directly to or near specific nerves to interrupt pain signals traveling to your brain. By targeting the source of pain signals rather than treating symptoms systemically, nerve blocks can provide significant relief for chronic pain conditions that haven’t responded adequately to oral medications or other treatments. Nerve blocks serve both therapeutic purposes—providing lasting relief—and diagnostic purposes—identifying which nerves are causing your pain.
At Madison Medical, our pain management specialists perform nerve block injections using imaging guidance to ensure precise placement. We evaluate your pain condition thoroughly to determine which nerves are involved and whether nerve block therapy can help you achieve better pain control and improved function.
How Nerve Block for Pain Works
Nerve block for pain works by interrupting nerve signal transmission:
- Local anesthetic numbs the nerve, stopping pain signals temporarily
- Corticosteroids reduce inflammation around irritated nerves
- The combination often provides extended relief beyond anesthetic duration
- Repeated blocks may provide progressively longer relief
- Breaking the pain cycle allows healing and rehabilitation
Types of Nerve Pain Injection
Nerve pain injection procedures target different areas depending on your condition:
Peripheral nerve blocks: Target specific nerves in your arms, legs, or trunk causing localized pain.
Sympathetic blocks: Address nerves of the autonomic nervous system involved in conditions like complex regional pain syndrome (CRPS).
Facet joint blocks: Target small joints of the spine that may be causing back or neck pain.
Selective nerve root blocks: Target specific spinal nerve roots causing radiating pain.
Conditions Treated with Nerve Blocks
Chronic Pain Conditions
Complex regional pain syndrome, neuropathic pain, and chronic post-surgical pain often respond to nerve block therapy.
Spinal Pain
Back and neck pain from facet joints or nerve root irritation may be diagnosed and treated with targeted blocks.
Headaches
Certain headache types, including occipital neuralgia, respond to nerve blocks targeting involved nerves.
