Sympathetic Nerve Block
This is an injection of local anesthetic and steroids into the area that surrounds the sympathetic nerves. The nerves run the length of the spine on both sides in a chain. Depending on where the injection is performed, the block can alleviate pain and improve blood flow to areas such as the arms, abdomen, and legs.
Patients with a history of cancer, diabetic neuropathy, phantom limb pain, reflex sympathetic dystrophy, poor circulation, and post-herpetic neuralgia of the legs can all potentially benefit from sympathetic blocks.
Common types of blocks include stellate ganglion injections, which help neck and arm pain, and lumbar ganglion blocks to decrease pain in the lower extremities. Sympathetic blocks also increase blood flow to the areas being targeted.
