How Long Does a Nerve Block Last?
If you've been living with persistent back, neck, joint, or nerve pain, even a few hours of relief can feel meaningful. But before considering an injection, it's natural to ask: How long does a nerve block last, and will the relief actually make a difference in your daily life?
The answer depends on the type of nerve block, the medication used, the nerve being targeted, and the condition being treated. Some people experience relief for a few hours, while others may notice improvement that continues for weeks or months. In certain cases, a nerve block also helps doctors identify the source of pain and plan the next stage of treatment.
At Innovative Pain and Wellness (IPW), nerve blocks are part of a personalized approach to pain management. The goal is not simply to perform an injection, but to understand what is causing your discomfort, target the appropriate nerves, and determine what may help you move forward.

How Long Can You Expect Relief From a Nerve Block?
There isn't one fixed timeline for every nerve block. The medication, injection location, and reason for treatment all matter.
Here's a general way to understand the possible timelines:
|
Type of medication or block |
What to expect |
|
Local anesthetic |
Often provides relief for a few hours; the duration depends on the medication and block used |
|
Local anesthetic with corticosteroid |
The anesthetic may work quickly, while the steroid may take several days to begin helping and can provide relief for weeks or months |
|
Diagnostic nerve block |
Usually provides temporary relief that helps assess whether a particular nerve is contributing to pain |
These are general ranges, not guarantees. A diagnostic block is not necessarily intended to provide lasting relief. Its main purpose is to help your physician understand the pain source. A therapeutic nerve block, on the other hand, is intended to reduce symptoms and may be part of a broader treatment plan.
It's also possible to experience a gap between the initial numbing effect and the anti-inflammatory effect of a steroid. During this time, pain may return temporarily before the steroid begins to work.
5 Factors That Affect How Long a Nerve Block Lasts
Two people can receive similar injections and experience different results. Here are some of the main reasons.
1. The Type of Nerve Block
Different nerve blocks target different nerves and pain patterns. An occipital nerve block, for example, may be considered for certain headache conditions, while other blocks may target nerves associated with back pain, joint pain, or complex regional pain syndrome (CRPS).
Because each procedure has a different target, the expected response and duration can vary.
2. The Medication Used
Local anesthetics temporarily interrupt pain signals. Their effects generally wear off within hours, although the exact duration depends on the medication and the type of block.
A corticosteroid may be included in certain therapeutic injections to reduce inflammation around the targeted area. Unlike a local anesthetic, it does not usually provide immediate numbing. Its effect may develop over several days and, in some cases, last longer.
Not every nerve block requires a corticosteroid. Your physician determines the medication based on the treatment goal and your individual needs.
3. The Location of the Injection
The nerve being treated and the surrounding anatomy can influence the response. A block targeting nerves around the head or neck may have a different purpose and expected outcome from one used for back, knee, or other joint-related pain.
The accuracy of medication placement also matters. At IPW, physicians use advanced imaging guidance to help deliver medication near the affected nerves.
4. The Underlying Condition
A nerve block may be considered for several pain conditions, including:
- Chronic back and neck pain
- Neuropathic pain
- Migraines and certain headache conditions
- Complex regional pain syndrome (CRPS)
- Joint-related pain
- Trigeminal neuralgia
The source of pain, how long you've experienced it, and whether inflammation or nerve irritation is involved can all affect the outcome.
5. Your Individual Response to Treatment
Your overall health, medical history, symptoms, and response to previous treatments can influence how much relief you experience. Some people respond well to one injection, while others may need additional treatment or a different approach.
This is why discussing your results with your pain management physician is important. The aim is to understand whether the block helped, how long the improvement lasted, and what that response means for your next steps.
Diagnostic vs. Therapeutic Nerve Blocks: Why the Difference Matters
Not every nerve block is performed with the same goal. Understanding the difference can help you set realistic expectations.
Diagnostic Nerve Block
A diagnostic nerve block helps your physician determine whether a specific nerve is contributing to your pain. A local anesthetic is injected near the suspected nerve, and your response is assessed over the expected numbing period.
If your usual pain decreases during that time, it may suggest that the targeted nerve is involved. If there is little or no change, your physician may need to investigate another possible source.
The relief may be short-lived, but the information can be useful when planning further treatment.
Therapeutic Nerve Block
A therapeutic nerve block is intended to manage pain. Depending on the condition and the type of injection, it may involve a local anesthetic, a corticosteroid, or another medication selected by the physician.
The goal is to reduce pain signals or inflammation and help you function more comfortably. The duration of relief varies, and the injection may be one part of a broader pain management plan.
What to Expect During a Nerve Block at IPW
Knowing what happens during the appointment can make the process feel more manageable.
At Innovative Pain and Wellness, treatment begins with understanding your symptoms rather than choosing an injection based on pain location alone.
1. Reviewing your pain history
Your physician will discuss where the pain occurs, when it started, what makes it worse, and how it affects everyday activities. Previous treatments, medical history, and relevant imaging may also be reviewed.
2. Identifying the appropriate nerve
Based on your evaluation, the physician determines whether a nerve block may be appropriate and which nerve or group of nerves should be targeted. The team also considers whether the goal is diagnostic or therapeutic.
3. Planning the injection
The injection area is cleaned, and the physician uses advanced imaging guidance to help position the needle accurately. A local anesthetic may be used to numb the skin before the medication is delivered.
4. Monitoring your response
After the injection, you may be asked to rest briefly while the team monitors how you are feeling. Your physician will provide instructions based on the specific procedure and medication used.
Nerve blocks are generally minimally invasive procedures, but the experience and aftercare can differ depending on the type of block.
What Should You Expect After a Nerve Block?
It is common to notice temporary changes around the injection site or in the area supplied by the targeted nerve.
Depending on the block, you may experience:
- Temporary numbness or tingling
- A feeling of heaviness in the treated area
- Mild soreness or tenderness around the injection site
- Temporary weakness, depending on the nerve targeted
- A short-term increase in discomfort after the injection
Follow your physician's instructions about activity, driving, and medication. Avoid putting yourself at risk while an area is numb or weak, since you may not notice an injury as easily.
Contact your physician if you experience new or worsening weakness, persistent or unusual numbness, increasing redness or swelling, drainage, fever, or severe pain. Seek urgent medical attention for serious or rapidly worsening symptoms.
What Happens When a Nerve Block Wears Off?
A common concern is that pain will return as soon as the medication stops working. This can happen, particularly when the block is intended to provide temporary relief or help identify the source of pain.
If your symptoms return, it does not automatically mean the procedure failed. Your response gives your physician useful information.
Here is what the next steps may look like:
1. Track the relief: Note when you first felt a difference, how much your pain improved, and when symptoms started returning.
2. Discuss your response: Share these details during your follow-up so your physician can assess whether the block achieved its intended goal.
3. Review the treatment plan: Depending on your response, your physician may discuss another injection, additional evaluation, or a different treatment option.
4. Consider the broader approach: Medication management, physical therapy, or other interventional pain treatments may be considered when appropriate.
A nerve block should not be repeated automatically whenever pain returns. The decision depends on the type of block, the benefit you experienced, your medical history, and the recommended treatment interval.
How Often Can You Get a Nerve Block?
There is no universal schedule for repeating nerve blocks. Some diagnostic blocks are performed as part of a specific evaluation, while therapeutic injections may be considered again depending on how well the previous treatment worked.
Before recommending another injection, your physician may consider:
- How much pain relief you experienced
- How long the relief lasted
- Whether your daily activities improved
- The type of medication used
- The potential risks of repeating the procedure
- Whether another treatment may be more appropriate
If the first nerve block provides little or no benefit, repeating the same procedure may not be the best next step. Your physician may reassess the diagnosis or discuss another way to manage your pain.
When Should You Consider Nerve Blocks in Scottsdale, AZ?
If persistent pain is affecting your sleep, movement, work, or everyday routine, a pain management evaluation may help you understand your options.
At Innovative Pain and Wellness, nerve blocks may be considered for patients experiencing chronic back or neck pain, neuropathic pain, migraines and certain headaches, CRPS, joint pain, or trigeminal neuralgia.
The physicians take an individualized approach, using your symptoms, medical history, and treatment goals to determine whether a nerve block is appropriate. With advanced imaging guidance, the team focuses on precise medication placement and a treatment plan that addresses your specific pain concerns.
A nerve block may offer temporary relief, provide diagnostic information, or become one part of a broader strategy to improve comfort and function. Your physician will discuss what you can realistically expect and whether another treatment may be needed.
