How Many Hours Does a Nerve Block Last for Herniated Disc Pain?
A nerve block for herniated disc pain usually lasts 8 to 36 hours. This timing varies based on the type of injection, the level of nerve inflammation, and the severity of your disc irritation. For extended relief, doctors use medium-acting spinal nerve blocks that can last up to three months. However, long-term spinal nerve blocks can last up to two years.

What Is the Typical Duration of Pain Relief From a Nerve Block?
Most patients experience pain relief from a nerve block for a few hours to several months. The exact duration depends on the type of anesthetic and the location of the irritated spinal nerve. Additionally, if the nerve block reduces inflammation around the nerve, the duration of pain relief may be extended.
Here are the typical durations of pain relief based on the type of nerve block:
- Short-acting nerve blocks typically provide temporary relief for 8 to 36 hours.
- Medium-acting spinal nerve blocks can ease symptoms for several weeks to three months.
- Epidural nerve blocks may relieve pain for several weeks or longer when inflammation decreases.
- Long-acting spinal nerve blocks can provide pain relief for one to two years but carry a higher risk.
Can Repeated Nerve Blocks Extend The Duration of Pain Relief?
Yes, repeated nerve blocks can extend the duration of pain relief. This is because each injection reduces nerve inflammation and decreases the pressure caused by a herniated disc. They are often recommended when symptoms return after the initial treatment. However, to limit potential long-term side effects, your doctor typically limits steroid-based injections.
In addition, according to the International Journal of Orthopaedics Sciences, researchers studied 120 patients diagnosed with lumbar disc herniation and radiculopathy. Their average pain score was 8.01 before treatment. After receiving selective nerve root block injections, patients’ pain score dropped to 3.97. The study also highlights that patients’ straight-leg-raise increased from 43° to 67° at six months.
What Types Of Nerve Blocks Are Available For Herniated Disc Pain?
For herniated disc pain, the most commonly used nerve block procedures are epidural steroid injections and selective nerve root blocks. Selective nerve root blocks target the specific nerve root and help block pain signals that travel into your back and leg. However, epidural injections deliver anesthetic medication around the irritated spinal nerve to reduce inflammation and provide temporary pain relief.
If these injections do not provide relief, your doctor may recommend the following therapeutic nerve blocks:
- Interlaminar epidural steroid injection: Delivers medication into the epidural space to ease widespread inflammation.
- Transforaminal epidural steroid injection: Targets the exact spinal nerve compressed by the herniated disc.
- Caudal epidural steroid injection: Reaches lower spinal canal nerves through the tailbone to reduce irritation.
- Medial branch block: Helps when facet joints contribute to your back and leg pain symptoms.
Why Does the Duration of Pain Relief From a Nerve Block Differ Among Patients?
Age, body weight, and nerve location are significant factors that affect the duration of pain relief after a nerve block. Other than that, the severity of your nerve irritation and underlying health conditions can also affect the duration of pain relief. For instance, diabetes can slow healing around the nerve, while obesity increases spinal pressure that reduces the effectiveness of the injection.
Moreover, the injection site, the presence of scar tissue, and the stability of your spine also affect the duration of the nerve block. In some cases, repetitive bending or heavy lifting can reduce the impact of the nerve block injection. At Total Orthopedics & Sports Medicine, our medical team reviews our medical history and assesses your age and work-related physical requirements. Then, we recommend the most effective injection based on your specific nerve irritation pattern. Contact us today to get an effective pain management plan.
Can Anxiety or Stress Reduce the Effectiveness of a Nerve Block?
Yes, anxiety or stress can reduce the effectiveness of a nerve block by increasing the overall pain sensitivity. When you take stress, your sympathetic nervous system activates your fight-or-flight response. It also makes your central nervous system more reactive to pain signals. Similarly, anxiety can also cause muscle tension around the irritated nerve, which increases pressure and reduces the benefit of your injection. As a result, the local anesthetic offers only limited symptom relief.
Tip: Practice slow, deep breathing before your injection to calm nerve tension and improve the results.
What Is the Success Rate of Nerve Blocks for Herniated Disc Pain?
The success rate of nerve blocks for herniated disc pain is generally high, especially for immediate short-term relief. According to a study published by Dovepress, 90.7% of 76 patients experienced immediate pain reduction after the procedure. Over a three-month follow-up, 28.9% of patients maintained long-term improvement, while 61.8% experienced recurring symptoms, and 35 patients ultimately required surgery. The study also supports nerve blocks as an effective treatment option when conservative care fails.
Can You Combine Nerve Blocks With Other Treatments for Lasting Relief?
Yes, you can combine nerve blocks with other treatments to achieve longer and more stable pain relief. You can use medications like NSAIDs or gabapentin to control pain and support consistent improvement after the injection. Your doctor may also recommend lifestyle adjustments such as weight control, proper ergonomics, and targeted core strengthening.
Additionally, the following supporting treatments can further enhance the benefits of nerve block:
- Regenerative injections (PRP)
- Stress-management techniques
- Spinal cord stimulation or nerve ablation
How Soon Can You Resume Exercise After a Nerve Block?
You can usually resume light activity the day after a nerve block injection if your pain begins to improve. You can start with gentle walking on the same day, as normal activities increase blood circulation and reduce stiffness. However, avoid strenuous exercise until the injection has stabilized, especially if the targeted nerve remains sensitive after treatment.
Additionally, your doctor may advise you to avoid heavy lifting for a few days to give the irritated nerve root time to calm down. After a few days, you can gradually add strengthening exercises as your symptoms improve. This gradual return prevents recurrence of pain and supports better long-term stability.

FAQs
What Is a Permanent Nerve Block for Back Pain?
A permanent nerve block for back pain refers to surgical procedures that destroy pain-carrying nerves to provide permanent pain relief. You may get different types of nerve block procedures, such as neurectomy or rhizotomy, depending on your condition. These methods can treat chronic pain conditions but may also cause nerve damage. Therefore, permanent nerve blocks are not recommended.
Is Swelling or Soreness Normal After Receiving a Nerve Block?
Yes, swelling or soreness is normal after receiving a nerve block, especially around the injection site. You may also experience temporary numbness as the pain medication takes effect. These symptoms usually improve within a few days and do not affect the overall benefit of the injection. However, you should contact your doctor if swelling increases or persists longer than expected.
Can a Nerve Block Help Diagnose the Source of Disc Pain?
Yes, a nerve block can help diagnose the source of disc pain by identifying how your irritated nerve cells respond to the injection. This process is known as diagnostic nerve blocks, and it helps your doctor confirm the underlying condition that causes your symptoms. After the injection, if you experience any temporary relief, it helps identify the exact location of the herniated disc.
Can Lifestyle Factors, Such as Smoking, Affect Nerve Block Effectiveness?
Yes, lifestyle factors like smoking can impact the effectiveness of the nerve block because these factors affect your body’s response to medication. Smoking increases inflammation and restricts blood flow, which can reduce pain relief for disc-related nerve irritation. It can also reduce the effectiveness of sympathetic nerve blocks used in targeted treatment plans.
How Many Nerve Block Injections Will I Need?
You may need two to four nerve block injections, depending on the level of relief you experience after each treatment. Your doctor reviews the duration of benefit from each block before planning further treatment options. For patients with recurring flare-ups, repeat nerve block injections are commonly advised.
Can Nerve Blocks Provide Permanent Pain Relief?
No, most nerve blocks cannot provide permanent pain relief because the injected medication offers only temporary relief from nerve irritation. These injections reduce inflammation and calm nerve activity, but their benefit fades over time. However, a permanent solution to pain is possible only with neurolytic or preemptive nerve blocks, which intentionally destroy targeted nerves.
How Quickly Do Nerve Blocks Start Working?
Nerve blocks usually start working within minutes of the injection, giving you fast relief from disc-related pain. The timing varies based on the medical procedure, the spinal anesthesia used, and your individual body’s response. Additionally, some injections calm the irritated spinal nerve quickly, while others take longer to ease pressure near the spinal cord.
