What are the Spinal Facet Joints?

  • Spinal facet joints are a pair of joints on the posterior aspect (back side) of the spine.

  • These small joints assist in the movement and stability of the spine.

  • These joints can also be a source of pain in the neck/back.


What is a Facet Joint Injection (FJI)?

  • An FJI often places an anti-inflammatory medication directly into the joint.

  • Goal: Reduce joint inflammation in order to reduce pain.

  • This current page focuses on FJIs using steroid medications.

  • FJIs using Regenerative Medications (Platelet Rich Plasma, Stem Cells)

    • These treatments may help regenerate damage inside the joint.

    • This may possibly treat the cause of joint pain, not just treat inflammation/symptoms.

    • See the specific pages on Regenerative Medicine for more details.


Are Facet Joint Injections Painful?

  • Most individuals tolerate FJIs well with little discomfort.

  • If any discomfort is felt, it is usually short-lived and tolerable.

  • If you feel any significant discomfort during the procedure, tell your doctor.


Can I be put to “Sleep” for an FJI?

  • Stone Med DOES NOT recommend general anesthesia for any spinal procedure.

  • Risk of complications increases if an individual is “put to sleep”.


Can I have any Sedation for an FJI?

  • Individuals may choose to have “light” IV sedation for their injection.

  • Light sedation is not designed to put you completely to sleep.

  • Goal of Sedation: Reduce pain/anxiety enough to make the procedure more comfortable

  • Decision to have sedation is up to the individual having the procedure, not the doctor.


Are there any Risks with IV Sedation?

  • IV sedation increases the risk of nausea and vomiting during the procedure.

  • Vomiting while sedated may cause you to aspirate (inhale) some vomit into your lungs.

    • Could cause a serious pneumonia, requiring antibiotics and possible hospitalization.

  • Risk of aspiration is significantly reduced if you do not eat or drink prior to the procedure.

    • Do not eat for 6 hours prior to the procedure.​

    • Do not drink for 4 hours prior to the procedure.


Will an FJI make all my Pain go Away?

  • Goal: Reduction of pain enough to allow the individual to regain quality of life and function.

  • While it is possible to obtain complete pain relief after an FJI, this is not always possible.


How Long until the FJI Starts to Work?

  • Most individuals start to feel pain relief within 1-3 days after the steroid injection.

  • In some cases, it may take up to 7-10 days after the injection to feel any benefit.

  • Maximum improvement usually occurs around 7-14 days after the injection.


How Long will Pain Relief Last after an FJI?

  • Everyone responds differently to steroid injections.

  • An FJI works by reducing inflammation inside the facet joint.

    • Pain often improves as joint inflammation decreases.

    • Pain relief often lasts as long as inflammation does not return.

  • FJIs are basically “Band-Aids” designed to treat symptoms of inflammation.

    • Injections do not heal/remove the actual cause of the inflammation.

    • If the injection reduces pain for a long period of time, this can be a great Band-Aid.

  • Unfortunately, pain always has potential to return in the future if inflammation returns.

    • If inflammation returns quickly after the injection, pain may also return quickly.

    • If inflammation never returns, pain may resolve forever.

  • A “Good Response” for an FJI is considered at least 3-4 months of significant pain relief.

    • If symptoms return, another FJI may be needed to reduce inflammation again.

  • Medications, exercise and/or therapy can often enhance/prolong the benefit of the FJI.


How many FJIs will I need?

  • Number of FJIs needed depends on the response to the injections.

    • If the first FJI provides significant benefit, then no more injections are needed. 

    • If the first FJI helps, but pain remains, a second FJI may provide “additive” benefit.

    • In some cases, three FJIs may be needed to achieve the desired reduction of pain.

  • Even if the FJI helps reduce pain significantly, pain may return again in the future.

    • If this occurs, it may be necessary to repeat the FJIs again.

  • Steroid medications and injections are not without risk.

    • Recommendation: Limit number of FJIs to no more than 3-4x per body region per year

    • As with any medical treatment, the minimal number of FJIs needed to have the desired effect is recommended.


What if the FJI does not Help my Pain?

  • Possible reasons why an FJI may not have helped reduce pain:

    • Some individuals require more than one FJI to get adequate pain relief.

    • Sometimes pain is not due to inflammation.

      • FJIs work better when pain is due to inflammation.

    • There may be another cause of pain in the spine.

      • An FJI only treats pain related to the facet joints.

    • Individuals with severe spinal conditions may not respond well to injections.

      • Sometimes, more aggressive treatments like surgery, are better treatment options.

  • If the FJI does not help your pain, your provider will discuss other treatment options.


What are the Risks of an FJI?

  • All injections have possible risks, side effects, and complications.

    • When performed correctly, all the following risks are rare.


  • FJIs usually do not cause significant discomfort during or after the procedure.

  • Any increased discomfort usually lasts less than 24 hours.


  • Superficial bruises resolve without any specific treatment.

  • More common in older individuals and those taking blood thinning medications.


  • Minimal risk, as we thoroughly clean the skin prior to every injection.

  • All needles are brand new (never reused) and opened just prior to the injection.


  • Excessive bleeding is rare, even if the needle hits a deeper blood vessel near the spine.

    • Any bleeding usually stops on its own without complications.

  • Risk of Bleeding increases if:

    • You have a genetic bleeding disorder.

    • You are taking medications that thin your blood.


  • Very Rare Complications

  • Direct Nerve Trauma from the Needle is very unlikely.

    • Risk is higher if the patient is “put to sleep” for the injection.

  • Damage to the anterior spinal artery could result in a spinal cord injury.

    • This artery supplies blood to the front of the spinal cord.

    • Contrast is injected to ensure the needle is not in a major artery.


  • Exceptionally Rare Complications

  • Even if all precautions are taken, these severe complications are never reduced to zero.


What are the Side Effects of Steroids?

  • Steroid medications have many potential side effects.

  • Steroid Injections usually cause less side effects than Steroid Pills.

  • Common Steroid Side Effects: Usually Mild and Temporary

    • Flushing of the Skin

    • Indigestion/Upset Stomach

    • Increased Appetite

    • Increased Blood Glucose Levels (See Section Below for Diabetic Patients)

    • Difficulty Sleeping/Insomnia

    • Increased Anxiety/Restlessness

    • Racing/Pounding Heart (Tachycardia, Palpitations)

    • Headaches

  • Rare, Severe Steroid Complications

    • Thinning of the Skin and Soft Tissue at the Injection Site

    • Weakening/Rupture of Tendons

    • Hypopigmentation (Whitening/Lightening) of the Skin around the Injection Site

    • Damage of Cartilage

    • Thinning of Bone (Osteoporosis)

    • Death of Bone (Osteonecrosis)

  • Diabetes Patients

    • Steroid medications will temporarily increase blood glucose levels.

    • If you use insulin, you may need to adjust your insulin dosing temporarily.

    • Be sure to discuss this with your primary care doctor or endocrinologist.

  • To reduce risk of steroid medications, it is best to limit the dose of steroids.

    • For injections, we recommend limiting FJIs to no more than 3-4 injections per year.

      • Less injections mean less risk of potential complications.

    • Although it seems like common sense, steroid injections should only be used if they provide significant benefits for pain.

      • Do not continue to get steroid injections if they do not help you.


Do I Need to Stop any Medications for the FJI?

Blood Thinning Medications

  • Blood thinners are often stopped about 3-7 days prior to spinal injections.

  • Tell your provider if you are taking any blood thinning medications.

    • Examples: Coumadin (Warfarin), Pradaxa, Eliquis, Xarelto, Plavix, Aspirin, etc.

  • These medications are usually prescribed for serious medical conditions.

    • We will contact your prescribing doctor to ensure it is safe to temporarily stop these medications for your procedure.

Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)

  • NSAIDs are often stopped about 5-7 days prior to spinal injections.

    • These medications can increase your risk of bleeding.

  • Tell your provider if you are taking any NSAIDs.

    • Examples: Ibuprofen (Advil, Motrin), Naproxyn (Aleve, Naprosyn), Indocin (Indomethacin), Lodine (Etodolac), Relafen (Nabumetone), Meloxicam (Mobic), Diclofenac (Voltaren), etc.

  • Celebrex (Celecoxib) is an NSAID that does not significantly increase the risk of bleeding.

    • Celebrex does not have to be stopped prior to spinal injections.


  • Many natural supplements can affect clotting pathways, increasing the risk of bleeding.

  • For safety, please stop taking supplements for at least 5 days prior to your injection.

    • Examples: Fish Oil, Vitamin E, Ginko Biloba, Ginseng, Garlic, St. John’s Wort

Other Medications

  • Do not stop taking any medications unless you are specifically told to stop.

  • If you have any questions about taking a certain medication, ask your provider.
