Key Takeaways
- Some patients feel relief within minutes of a nerve block, while for others, full effects may take a few days to develop.
- Results vary based on the type of nerve block, the medications used, and each patient's individual response.
- The first 24–48 hours often involve a mix of numbness from the anesthetic, temporary soreness, and gradually improving relief.
- Some patients achieve lasting results from a single injection, while others benefit from a series of treatments.
- The Physicians Spine & Rehabilitation Specialists provide personalized nerve block treatment for patients throughout the greater Atlanta area, and those curious about this option can request an appointment to learn what to expect for their specific condition.
How Nerve Blocks Work
A nerve block is an injection of medication near a targeted nerve or group of nerves, designed to interrupt pain signals before they reach the brain. Depending on the type of nerve block, the injection may include a local anesthetic alone or a combination of anesthetic and steroid medication.
According to the Cleveland Clinic, the effects of a nerve block injection are usually quick, but nerve blocks are often a temporary fix — some patients respond well to a single injection, while others need multiple treatments to manage their symptoms effectively.
When Patients May Begin Feeling Relief
Relief timelines can vary depending on the type of nerve block and the medications used:
- Immediate relief: The local anesthetic component often provides fast, short-term pain relief within minutes of the injection.
- Temporary rebound: As the anesthetic wears off — often within a few hours — some patients notice their original pain return briefly before the treatment fully takes effect.
- Longer-term relief: If a steroid medication is included, it typically begins reducing inflammation over the following days, offering more lasting pain relief.
Why Results Vary From Person to Person
Several factors influence how quickly — and how well — a nerve block works, including:
- The specific nerve or condition being treated
- The type and dosage of medication used
- Whether inflammation or nerve irritation is the primary source of pain
- Individual differences in how each patient responds to treatment
Because of this variability, your provider may recommend a diagnostic nerve block first — a smaller, more targeted injection used to confirm that a specific nerve is the true source of pain before moving forward with additional treatment.
What to Expect During the First 24–48 Hours
| Timeframe | What You Might Experience |
|---|---|
| Immediately after injection | Numbness or reduced pain from the local anesthetic |
| A few hours later | Anesthetic wears off; some soreness or return of pain is common |
| 1–2 days later | Gradual improvement as any steroid medication begins working |
| 3–5 days later | More noticeable, longer-lasting pain relief for many patients |
Most patients can resume normal activities the same day or the next, though your provider may recommend avoiding strenuous activity for a short period after the procedure.
Temporary Side Effects and Recovery Tips
Mild, short-term side effects are common after a nerve block and typically resolve on their own. These can include:
- Soreness or bruising at the injection site
- Temporary numbness in the treated area
- Mild fatigue on the day of the procedure
To support recovery, patients are generally advised to:
- Rest for the remainder of the day following treatment
- Apply ice to the injection site if recommended by their provider
- Avoid strenuous activity for 24 hours
- Monitor for any unusual symptoms and contact their provider with questions
When to Follow Up If Symptoms Continue
If pain returns fully after the anesthetic wears off and doesn't improve over the following days, it doesn't necessarily mean the treatment failed — it may simply mean a series of injections or a different approach is needed. Patients should follow up with their provider if:
- Pain relief doesn't improve at all within a week
- Pain worsens significantly after the procedure
- New symptoms, such as increased numbness or weakness, develop

Frequently Asked Questions
How long does it take for a nerve block to start working?
Many patients feel some relief within minutes due to the local anesthetic, though full, longer-lasting effects from any steroid medication may take a few days to develop.
What can I expect after a nerve block injection?
It's common to experience temporary numbness followed by a brief return of pain as the anesthetic wears off, with gradual improvement over the following days.
How many nerve block injections will I need?
This varies by patient and condition. Some people achieve lasting relief from a single injection, while others benefit from a series of treatments over time.
What should I do if my nerve block isn't working?
If you don't notice improvement within about a week, follow up with your provider. They can determine whether additional treatment, a different type of injection, or another approach is needed.
