Facet Joint Injections: Benefits, Risks, and Results

Facet joint injections are a minimally invasive, outpatient treatment for neck and back pain caused by irritated or arthritic facet joints. They deliver medication directly to the source of pain to reduce inflammation and ease discomfort. They also help confirm where pain is coming from, which guides the rest of a treatment plan.

Understanding Facet Joints and Back Pain

What Are Facet Joints?

Facet joints are small, paired joints on the back of each vertebra. They connect one spinal bone to the next and guide how the spine bends, twists, and extends. Each joint is lined with cartilage and surrounded by a capsule of fluid that keeps movement smooth.

These joints run the full length of the spine. That is why facet problems can cause pain in the neck, the mid-back, or the low back.

How Facet Joints Cause Back Pain

Facet joints wear down over time, just as knees and hips do. Arthritis, injury, poor posture, and repeated strain can thin the cartilage and inflame the joint. Car accidents and falls can also injure the facet joints through sudden whiplash or impact.

Facet pain often feels like a deep ache on one or both sides of the spine. It tends to worsen when leaning backward, twisting, or standing for long periods. Pain may spread into the shoulders, buttocks, or upper thighs, though it usually does not travel below the knee the way sciatica does. These injections are used to treat pain from facet joint arthritis, injury, or inflammation, and results can last from weeks to months.

How Facet Joint Injections Work

A facet joint injection delivers medication directly into or near the painful joint. The medication usually combines a local anesthetic for fast numbing with a corticosteroid that calms inflammation over the following days.

The injections serve two purposes. First, they can relieve pain. Second, they act as a diagnostic test. If a patient feels strong relief after the injection, that result confirms the facet joint is a main source of the pain. A related option, the medial branch block, numbs the small nerves that carry pain signals from the joint and is used in a similar way to pinpoint the cause.

At our office, Dr. Bruce M. Fischer, an anesthesiologist and pain management specialist, performs these injections as part of our interventional pain management services.

Conditions Treated with Facet Joint Injections

Facet joint injections may help patients with:

• Facet joint arthritis or spinal osteoarthritis

• Chronic low back pain linked to the facet joints

• Neck pain from facet joint inflammation

• Whiplash and other injuries from car accidents

• Spondylosis, or age-related wear of the spine

• Back pain after a slip and fall

They are one of several options we use for neck and back pain.

What to Expect During the Procedure

Preparing for the Injection

Before recommending an injection, Dr. Bruce M. Fischer reviews your symptoms, medical history, and any imaging. This step helps confirm that the facet joints are a likely cause of your pain. It also rules out conditions that would respond better to another treatment.

You will receive clear instructions before your appointment. Many patients are asked to arrange a ride home, since the anesthetic can cause temporary numbness or weakness.

The Injection Process

Facet joint injections are an outpatient treatment. Most patients go home the same day. Imaging guidance is used so the medication reaches the right joint. Patients usually feel pressure and brief discomfort rather than sharp pain. The visit is short, and you will rest for a little while afterward before heading home.

Blood Thinners and Safety Considerations

Tell us about every medication and supplement you take. Never stop a prescribed blood thinner on your own. Our team will coordinate with you and, when needed, with the doctor who prescribed it.

Let us know if you have diabetes, since steroids can raise blood sugar for a few days. Also tell us about any allergies, an active infection, or a possible pregnancy.

Benefits of Facet Joint Injections

Targeted Pain Relief

Facet joint injections send medication straight to the source of the pain. Oral pain medicine travels through the whole body. A targeted injection uses a smaller dose in one specific area, which can mean stronger relief with fewer body-wide effects.

The diagnostic value is a benefit on its own. Knowing exactly which joints are causing pain helps us build a plan that addresses the real problem rather than guessing.

Improved Mobility and Quality of Life

When pain drops, movement gets easier. Many patients find they can sleep better, sit longer, and return to work, exercise, and daily tasks. This window of relief is also the right time to start rehabilitation.

We often pair injections with physical therapy and chiropractic care. Strengthening the core and improving posture can help protect the facet joints and extend the benefits of the injection.

Common Side Effects

Most side effects are mild and short-lived. They may include:

• Soreness or bruising at the injection site

• A temporary increase in pain for a day or two

• Short-term numbness or weakness from the anesthetic

• Facial flushing or a warm feeling

• Trouble sleeping for a night or two

• Higher blood sugar in patients with diabetes

These effects usually fade within a few days. Call us right away if you notice fever, severe or worsening pain, redness or swelling at the site, or new weakness in your arms or legs.

Repeated steroid injections over time can affect bone and soft tissue. For this reason, the number of injections in a year is usually limited.

Results and Recovery

When Will I Feel Relief?

Some patients feel relief within minutes to hours because of the local anesthetic. That early numbness can wear off later the same day, and pain may briefly return. The steroid then starts working, usually within two to seven days.

How Long Do the Benefits Last?

Results vary from person to person. Some patients have relief for a few weeks. Others have relief for several months or longer. Results tend to last longer when the injection is combined with exercise, posture changes, and an active rehab plan.

If an injection gives strong but short relief, that result still has value. It confirms the source of pain and helps guide next steps.

Post-Injection Care and Follow-Up

Plan to take it easy for the rest of the day. Most patients return to normal activity within a day or two. You may use ice on the injection site for soreness. Avoid soaking in a bath, pool, or hot tub for the first day or two.

Keep a simple pain journal for the first week. Note your pain level and what activities feel easier. This record helps Dr. Bruce M. Fischer judge how well the injection worked during your follow-up visit and decide whether further treatment makes sense.

Is a Facet Joint Injection Right for You?

Who Is a Good Candidate?

You may be a good candidate if:

• Your neck or back pain has lasted longer than a few weeks

• Pain worsens with twisting, bending backward, or standing

• Rest, medication, or therapy has not given enough relief

• Imaging or an exam points to facet joint arthritis or injury

• You want to avoid or delay more invasive options

Facet injections may not suit patients with an active infection, a bleeding disorder, or an allergy to the medications used.

When to Consult a Specialist

See a specialist if back or neck pain limits your sleep, work, or daily routine, or if it continues after an accident or fall. Seek care right away for pain with numbness, leg weakness, or loss of bladder or bowel control. Dr. Bruce M. Fischer will evaluate your condition and explain which options fit your goals, whether that means injections, regenerative medicine, or another approach. Side effects are usually mild, and relief can last weeks to months. Combined with therapy and movement, these injections can help patients in Boca Raton return to daily life with less pain.
