Selective Nerve Root Blocks

Chronic pain that results from sciatica or other conditions related to nerves can affect one’s life. It can incapacitate an individual and leads to poor quality of life. Sometimes, it may also results in depression. Doctors suggest Selective Nerve Root Blocks (SNRBs) for alleviating nerve related pain. Some people neglect this condition and avoid seeking timely medical attention. In case, you have been suffering from chronic back pain, seek medical advice without delay. SNRBs can isolate actual cause of the pain and create the best treatment plan.

As per the results of the American Medical Association research, it is revealed that the main reason of back pain is disability among American workers. About half of all adults in the United States get chronic pain at some point in their lifetime.

Chronic and acute pain can be distinguished by the duration of the pain. Typically, pain that lasts more than three months is diagnosed and treated as chronic. It is crucial to seek treatment for chronic pain to relieve its symptoms and improve the overall quality of life. It is also important to note that chronic pain can lead to depression, and therefore, it is necessary to understand all the potential effects it can have.

Selective nerve root blocks are an effective method for identifying the precise location and cause of chronic pain. The procedure involves administering a combination of an anesthetic and steroids to the area thought to be the source of discomfort. The patient is then asked to perform their normal range of motions, including those that usually elicit pain. If there is no pain during the exercises, the location of the inflammation can be pinpointed, allowing for targeted treatment.


As X-rays and MRIs do not provide a complete picture of nerve conditions, nerve testing is essential to locate abnormalities in the nervous system. EMG and NCS tests are used to map the electric impulses of nerves and create visual representations in the form of graphs. By analyzing these graphs, a physician can detect any abnormalities and identify problematic nerves. The first injection is often used as a diagnostic test, with a small dose of local anesthetic injected to determine whether pain relief occurs. If so, the targeted nerves can be identified as the source of pain, and a more potent dose of corticosteroid or radio frequency can be administered as long-term therapy.

Recovery From A Cervical Selective-Nerve-Root Block

Following a cervical selective-nerve-root-block procedure, patients typically go home on the same day and can usually resume work the following day. Pain relief is often experienced immediately after the procedure, although it may temporarily worsen for a day or two before subsiding. This is a normal occurrence. Most patients experience complete relief from pain within a week after the procedure.

Risks and Complications

The sympathetic nerve block procedure is considered to be a safe method of treatment. Through the use of advanced interventional techniques, including live imaging with X-ray machines and contrast dye, physicians can accurately locate and target the affected nerves with minimal risk of complications.
