Diagnostic Nerve Blocks
Precise identification of pain sources through targeted nerve assessment
About Diagnostic Nerve Blocks
Diagnostic nerve blocks are specialized procedures where local anesthetic is injected near specific nerves or nerve groups to determine if they are the source of a patient's pain. Unlike therapeutic injections that aim to provide long-term relief, diagnostic blocks are primarily investigative tools that help Dr. Hemani pinpoint the exact source of pain, leading to more targeted and effective treatment plans.
Diagnostic Precision
Identifies specific nerves responsible for transmitting pain signals
Targeted Approach
Guides development of customized treatment plans
Investigative Tool
Helps rule out or confirm suspected pain sources
Who Can Benefit
Diagnostic nerve blocks are particularly beneficial for patients with:
- Undiagnosed chronic pain conditions
- Pain that has not been adequately diagnosed with imaging or other tests
- Complex pain patterns involving multiple potential sources
- Patients considering more invasive procedures who need confirmation of a pain source
- Those with pain that doesn't match typical patterns or imaging findings
Dr. Hemani will conduct a thorough evaluation to determine if diagnostic nerve blocks are appropriate for your specific condition and which nerves should be targeted.
Common Diagnostic Nerve Blocks
Dr. Hemani performs various types of diagnostic nerve blocks, each targeting specific areas and conditions:
Medial Branch Blocks
Target the small nerves that supply the facet joints of the spine. Used to diagnose facet joint pain and determine if radiofrequency ablation might be beneficial.
Selective Nerve Root Blocks
Target specific spinal nerve roots to identify which nerve is causing radiating pain, numbness, or weakness in the arms or legs.
Sympathetic Nerve Blocks
Target the sympathetic nervous system to diagnose complex regional pain syndrome (CRPS) and other sympathetically-mediated pain conditions.
Sacroiliac Joint Blocks
Target the sacroiliac joint to determine if it's the source of lower back, buttock, or leg pain.
Peripheral Nerve Blocks
Target specific peripheral nerves to diagnose conditions like occipital neuralgia, intercostal neuralgia, or other nerve entrapment syndromes.
Differential Spinal Blocks
A sequential series of blocks at different levels of the spine to help differentiate between various pain generators in complex cases.
