Sciatica pain can be overwhelming—sharp, shooting, and persistent. Many patients in Texas seek long-lasting relief that doesn't require immediate surgery. A spinal nerve block injection in San Antonio, TX, is often recommended as one of the most effective non-surgical treatments. But does it truly work? How quickly does it help? And is it right for you?

At Brain and Spine Institute, San Antonio, Texas, our specialists use advanced image-guided nerve block techniques to help patients reduce pain, restore function, and return to their daily activities with confidence. This blog explains everything you need to know before choosing this treatment.

What Is Sciatica?

Sciatica refers to pain that travels along the path of the sciatic nerve—from your lower back to the hips, buttocks, and down each leg. This pain is typically caused by:

• Herniated disc

• Spinal stenosis

• Degenerative disc disease

• Bone spurs

• Muscle inflammation

• Nerve compression from injury or posture issues

Sciatica can feel like:

• Sharp, burning pain

• Tingling or numbness

• Muscle weakness

• Pain that worsens with sitting or standing

For many patients, over-the-counter medications or physical therapy provide only temporary relief. When sciatica becomes severe or persistent, nerve block injections become a practical next step.

What Is a Spinal Nerve Block Injection?

A spinal nerve block injection involves delivering a combination of local anesthetic and anti-inflammatory medication around the inflamed nerve root. This blocks the transmission of pain signals from the irritated nerve to the brain.

At Brain and Spine Institute in San Antonio, the procedure is performed using fluoroscopy or ultrasound-guided imaging, ensuring accuracy and maximum pain relief.

How Does It Help Sciatica?

Sciatica is often caused by swelling, compression, or inflammation around the nerve. A spinal nerve block:

1. Reduces inflammation around the pinched nerve

2. Blocks pain signals, offering instant relief

3. Allows muscles around the nerve to relax

4. Helps patients move more comfortably

5. Improves participation in physical therapy

6. Can prevent the need for spine surgery

For many patients, the injection acts as a reset for the nervous system—disrupting the pain cycle that has been affecting daily life.

Does a Spinal Nerve Block Injection Really Work for Sciatica?

Yes—for most patients, nerve block injections are highly effective, mainly when sciatica pain is caused by nerve irritation or inflammation.

Effectiveness Breakdown:

• Instant relief: Many patients experience reduced pain within minutes or hours.

• Short-term relief: Relief can last from a few days to a few weeks.

• Long-term relief: When combined with physiotherapy, lifestyle changes, or additional injections, benefits may last several months or more.

• Diagnostic value: If the injection relieves pain, it confirms which nerve root is irritated.

Clinical studies and patient results consistently show that spinal nerve blocks significantly reduce sciatica symptoms and improve mobility.

Who Is a Good Candidate?

You may be a good candidate for a spinal nerve block injection if:

• You have had persistent sciatica pain for more than 4–6 weeks

• Medications or therapy haven't helped

• You want to avoid or delay spine surgery

• You experience severe pain that affects walking or sleeping

• Your MRI or X-ray shows nerve compression

• Pain radiates down your leg

• You prefer minimally invasive treatment options

At Brain and Spine Institute, our specialists evaluate your symptoms, scans, and medical history to ensure this treatment is proper for you.

What Happens During the Procedure?

The nerve block injection is a simple, outpatient procedure completed in 15–30 minutes.

Step-by-Step Process

1. Positioning: Lie comfortably on the table.

2. Cleaning: The injection area is sterilized to prevent infection.

3. Local anesthesia: A small injection of numbing medication is given to minimize discomfort.

4. Imaging guidance: The doctor uses fluoroscopy or ultrasound to locate the exact nerve.

5. Medication injection: A mixture of anesthetic + steroid is carefully injected.

6. Recovery: You rest for 15–20 minutes before going home.

Most patients report little to no discomfort during the procedure.

How Long Does the Relief Last?

Every patient responds differently, but the general results are:

• Immediate relief: 60–80% of patients

• Pain reduction for several weeks or months: Most patients

• Long-term relief: When combined with physiotherapy and lifestyle changes

• Repeat injections: Some patients may need 2–3 injections per year for continuous relief

Our specialists create a personalized treatment plan based on your symptoms and goals.
