Relief from the Injection:
It depends on the pain condition and the procedure that is being performed as well as the physical condition of the patient. A series of three lumbar selective nerve root injections or lumbar facet rhizotomy could last for a year or longer.

The relief is rarely immediate, it may take from 48 hours up to several weeks until you get relief.

You will have a full consultation and physical exam before or on the day of the procedure. If you have questions they will be answered at that time.

Follow-up will be two weeks after the end of injection or procedure.

If the procedure is not effective in treating your pain condition various medical management options will be offered for you to try. At times the relief may not be complete so a combination of medical and injection management may be necessary.

There are situations that might require surgical consultation. If that is the case, you will be referred to a highly qualified spine surgeon.

Pain is a warning system, alerting you that something is wrong your body. Neurons are specialized nerve cells that transmit pain signals are found throughout the skin and others.

Most forms of pain can be divided into two general categories: acute and chronic.

Acute pain is temporary. It can last a few seconds or longer but wanes as healing occurs. Some examples of things that cause acute pain include burns, cuts, and fractures.

Chronic pain, such as that seen in people with osteoarthritis and rheumatoid arthritis, ranges from mild to severe and can last a lifetime.

Procedures can vary completely in the type that are done but the basic premise is to find the nerve or joint that is painful and guide placement medication upon that region.
