5 Mistakes to Avoid After an Epidural Injection for Back Pain- and When Ketamine Infusions for Pain Management May Help

Epidural injections are given to combat nerve pain that travels from spine into the arms or legs. After receiving a shot, you must avoid lifting heavy objects for some days, driving immediately, or applying heat on the site.

Key Takeaways

• Follow Immediate Aftercare Rules: Avoid driving right away, submerging the puncture site in water, or applying direct heat to prevent infection and localized inflammation.
• Allow Time for Steroids to Work: The initial numbing agent wears off within hours, but the anti-inflammatory steroid takes 3 to 7 days (or up to 2 weeks) to deliver noticeable relief.
• Epidurals Target Inflammation, Not Centralized Pain: Injections fail when back pain shifts from local nerve inflammation to centralized or neuropathic pain processing.
• Ketamine Reboots the Central Nervous System: Ketamine infusions help where epidurals fail by blocking NMDA receptors, treating direct nerve pain, and reversing opioid tolerance.

Epidural steroid injections provide deep relief and your body moves freely. Well, getting the injection is half of the work done. The actual battle starts after the procedure as how a patient behaves actually matters. You need to be careful about certain areas during the recovery phase.

This article identifies the common mistakes that patients must avoid after obtaining epidural injections.

What Not to Do After Getting Epidurals for Back Pain

Here are the mistakes that you must avoid after getting an epidural injection for back pain.

1. Driving Home After the Procedure

You might feel fine after receiving an epidural shot but that does not mean that you will drive home by yourself. This is because local anesthetics result in temporary leg numbness while weakening your muscles.

Patients might feel dizzy after the procedure and that makes driving risky and unsafe. You must arrange someone to drive you home.

2. Applying Heat Directly on the Injection Site

A common household activity for pain management is heat application. This must be avoided after receiving epidurals because heat increases blood flow to the area that worsen local swelling while increasing inflammation at the puncture site.

You can consider ice pack wrapped in a thin towel for 15 to 20 minutes to apply on the site. Avoid hot packs and steam rooms.

3. Lifting Heavy Objects too Soon

The pain might go within a few hours but you must refrain from engaging in heavy exercises. But why? Well, this can irritate the fresh infection site, increase inflammation, and can result in sudden muscle spasms.

Remember, pushing too hard might re-injure your disc or nerve. Wait for a couple of days after getting an epidural injection for back pain and resume light regular activities after that.

4. Submerging in Water too Early

A common mistake that many patients commit after epidural injections for back pain is seeking relaxation in a warm bath or hot tub to ease soreness. Well, this should not be done.  As the needle leaves a small puncture wound on your skin, you should not submerge in water soon.

Avoiding submerging in water lowers the risk of bacterial infections. You need to stick to quick showers for the first two days.

5. Expecting Instant Relief

If you expect instant relief after receiving epidurals, then it is a mistake. Steroids take at least 3 to 7 days to start reducing pain and inflammation. In some cases, it might take up to 2 weeks.

Don’t feel anxious when the initial numbing starts wearing off after a few hours and the pain returns temporarily. Consult with your doctor to understand the probable timeline.

Why Epidural Injections Might Fail for Back Pain?

Epidural injections are effective in minimizing acute, mechanical nerve root inflammation. Like, a fresh herniated disc pressing on a nerve. This pain management option becomes ineffective when pain shifts from an inflammatory state to a centralized or neuropathic state.

With time, chronic back pain results in the alteration of how our central nervous system processes signals. This enhances pain even after local tissue inflammation subsides.

Why Ketamine Infusions can be a Good Option if Epidural Injections Fail?

Let’s understand why you can consider Ketamine infusions for pain management.

Targeting Central Sensitization

If your chronic back pain exists for months, it reaches the central sensitization state (becomes hyper-excitable). Structural swelling might decrease but pain signals fire continuously.

Ketamine blocks N-methyl-D-aspartate (NMDA) receptors while acting directly on the overall central nervous system. This reboots how the brain perceives chronic pain signals. Hence, this is a perfect replacement for epidurals as it only targets localized tissue inflammation at the nerve root.

Acknowledging Neuropathic Pain Directly

Steroids might not provide any relief if back pain stems from nerve damage or persistent disc pressure. Here, going for Ketamine infusions is a good consideration. The fundamental reason behind this is that Ketamine is potent for refractory neuropathic pain as it targets the neurotransmitter glutamate instead of inflammatory cytokines.

Breaking Opioid Tolerance & Hyperalgesia

If you are on a long-term opioid medication for back pain, there is a high chance of developing opioid-induced hyperalgesia*. Ketamine infusions for pain management is the right choice here. This is because it restores opioid sensitivity and that leads to lower drug doses to become more effective while minimizing pain hypersensitivity. 

* A condition where the medication makes the body more sensitive to pain.

Wrapping Up

After getting an epidural shot, patients must avoid driving on the procedure day, apply heat on the injection site, and lifting heavy objects too early. Ketamine infusion is a probable option if this treatment fails because it targets central sensitization, addresses neuropathic pain, and breaks opioid tolerance.
