Nerve Block - Medical Glossary

Understanding Nerve Block?

A nerve block interrupts pain signals between a nerve and the brain. It is commonly used to diagnose or treat pain conditions. The procedure can be therapeutic (for pain relief) or diagnostic (to identify the source of pain). Nerve blocks are usually administered under imaging guidance for precision.

Symptoms and Signs That May Require a Nerve Block?

Patients experiencing persistent pain from arthritis, sciatica, migraines, post-surgical pain, or cancer may benefit from a nerve block. Symptoms may include radiating pain, inflammation, muscle spasms, or nerve sensitivity that hasn’t responded well to other treatments like oral medications or physiotherapy.

Causes and Risk Factors That Lead to Nerve Block Usage?

Conditions causing chronic pain, inflammation, or nerve injury often lead to the use of nerve blocks. These include herniated discs, nerve compression, joint degeneration, or trauma. Risk factors include previous surgeries, spinal problems, autoimmune conditions, and poor response to standard pain management.

Treatment and Benefits of a Nerve Block?

Nerve blocks help manage pain, reduce inflammation, and improve mobility. The medication is injected near the target nerve, offering localized relief. Benefits include rapid pain reduction, fewer systemic side effects, and sometimes permanent relief in cases of nerve ablation. Repeat injections may be needed in chronic cases.

When to Seek Medical Help for Nerve Block Consideration?

Consult a healthcare provider if you have chronic or severe pain that limits daily activities and hasn't improved with conventional treatments. A nerve block may be suggested if your pain is localized and a specific nerve is suspected. Early assessment ensures better outcomes and reduced reliance on opioids.
