Cervical Sympathetic Nerve Block Injection

A Cervical Sympathetic Plexus Nerve Block Injection Can Help Us Diagnose Your Neck Pain

If you are experiencing pain in your neck, shoulders, or arms, our spinal doctors may recommend a cervical sympathetic nerve block injection as a means of pinpointing from where your pain is originating. This specific kind of nerve block can tell our doctors whether or not your sympathetic nerves are the cause of the pain you are experiencing. Pain in your neck, spine, hands, arms, and shoulders can all be caused by the sympathetic nerves. These nerves are responsible for bodily functions such as:

  • Heart rate
  • Controlling your blood vessels
  • Sweating
  • Pupil dilation
  • Moving food through intestines

If the nerves aren’t working correctly, they can create pain on either side of your body. A sympathetic nerve block inject is performed near the neck on the front of your body. If the injection works, you will get relief from your pain symptoms and it will confirm that your sympathetic nerves are responsible for your pain. Your doctor will then be able to recommend a course of treatment appropriate for your condition. While in most cases the pain relief will wear off as the nerve block does, some patients report pain relief that lasts much longer than the anesthetic.

What are the most common conditions treated by sympathetic nerve block injections?

There are a number of conditions that can be diagnosed and treated with a sympathetic nerve block injection, including:

  • Blood vessel spasms
  • Sweating excessively
  • Some chronic stomach pain
  • Complex regional pain syndrome
  • Raynaud’s syndrome


  • To see if you are a good candidate for a cervical sympathetic nerve block injection, take our pain evaluation questionnaire and someone from our office will follow-up with you as soon as possible.
