What Are Nerve Blocks?
A nerve block is an injection of medication near specific nerves to interrupt pain signals. Nerve blocks serve two important purposes: they help diagnose the source of pain by confirming which nerve is involved, and they provide therapeutic relief by reducing inflammation and pain transmission.
Dr. Ohanyan performs a variety of nerve block procedures using image guidance for precision, ensuring medication is delivered exactly where it's needed.
Types of Nerve Blocks
Selective Nerve Root Blocks
Target individual spinal nerve roots to diagnose and treat radicular (radiating) pain from the spine.
Occipital Nerve Blocks
Injections at the back of the head for migraines, tension headaches, and occipital neuralgia.
Medial Branch Blocks
Diagnostic blocks of the nerves supplying facet joints, often preceding radiofrequency ablation.
Trigger Point Injections
Target painful muscle knots (trigger points) in neck, back, and shoulders.
Stellate Ganglion Block
For complex regional pain syndrome (CRPS) and certain vascular conditions of the arm.
Intercostal Nerve Blocks
Treat chest wall pain from rib injuries, shingles, or post-surgical pain.
