The different kinds of nerve blocks...

During some pain management procedures the doctors will administer a nerve block which can aid in relieving the pain. Some of the blocks are diagnostic but can still help in relieving the pain.

Obviously the stellate ganglion blocks that I received for the damage to the left radial nerve would be included in these nerve blocks. Of course until I see the doctor I am unsure as to what is causing the shoulder pain. However I can promise that if the blocks are indeed the cause just like I refuse to have anymore ESI's for the back there is no way I will let them give me another block. If the shots themselves are the cause of the pain and scar tissue that is forming then why the heck would I let them do it a second time?



Pain Management:
Nerve Blocks

Often a group of nerves, called a plexus or ganglion, that causes pain to a specific organ or body region can be blocked with the injection of medication into a specific area of the body. The injection of this nerve-numbing substance is called a nerve block.

How Are Nerve Blocks Used?

Different kinds of nerve blocks are used for different purposes.

* Therapeutic nerve blocks are used to treat painful conditions. Such nerve blocks contain local anesthetic that can be used to control acute pain.
* Diagnostic nerve blocks are used to determine sources of pain. These blocks typically contain an anesthetic with a known duration of relief.
* Prognostic nerve blocks predict the outcomes of given treatments. For example, a nerve block may be performed to determine if more permanent treatments (such as surgery) to block the activity of a nerve would be successful in treating pain.
* Preemptive nerve blocks are meant to prevent subsequent pain from a procedure that can cause problems including phantom limb pain.

Nerve blocks can be used, in some cases, to avoid surgery.

Types of Nerve Blocks

Various areas of pain require different nerve block types. Below are a few of the available nerve blocks, followed in parentheses by some of the parts of the body for which they are used.

* Trigeminal nerve blocks (face)
* Ophthalmic nerve block (eyelids and scalp)
* Supraorbital nerve block (forehead)
* Maxillary nerve block (upper jaw)
* Sphenopalatine nerve block (nose and palate)
* Cervical epidural, thoracic epidural, and lumbar epidural block (neck and back)
* Cervical plexus block and cervical paravertebral block (shoulder and upper neck)
* Brachial plexus block, elbow block, and wrist block (shoulder/arm/hand, elbow, and wrist)
* Subarachnoid block and celiac plexus block (abdomen and pelvis)

Other Nerve Blocks

Other types of nerve blocks include:

* Sympathetic nerve block: A sympathetic nerve block is one that is performed to determine if there is damage to the sympathetic nerve chain. This is a network of nerves extending the length of the spine. These nerves control some of the involuntary functions of the body, such as opening and narrowing blood vessels.
* Stellate ganglion block: This is a type of sympathetic nerve block performed to determine if there is damage to the sympathetic nerve chain supplying the head, neck, chest or arms and if it is the source of pain in those areas. Although used mainly as a diagnostic block, the stellate ganglion block may provide pain relief in excess of the duration of the anesthetic.
* Facet joint block: Also known as a zygapophysial joint block, the facet joint block is performed to determine whether a facet joint is a source of pain. Facet joints are located on the back of the spine, where one vertebra slightly overlaps another. These joints guide and restrict the spines movement.

Side Effects and Risks of Nerve Blocks

* Elevated blood sugars
* Rash
* Itching
* Weight gain
* Extra energy
* Soreness at the site of injection
* Bleeding
* Death (in rare cases)

Although many kinds of nerve blocks exist, this treatment cannot always be used. If your pain isn't related to pain in a single or small group of nerves, nerve blocks may not be right for you. Your doctor can advise you as to whether this treatment is appropriate for you.
