Nerve blocks and epidurals stop working because they only block the pain signal. That signal often comes from a whole-body metabolic fire nobody measured, not from the finding on your MRI. The driver keeps sending the signal, so each block buys less relief than the last.
Epidural. Nerve block. Steroid shot. If you have had long-term spine or joint pain for any length of time, you have likely been offered at least two of these. It is worth noticing what they have in common.
They are all designed to do one thing: block the signal.
Do epidurals and nerve blocks fix the cause of pain?
How you frame it matters more than it might seem. If pain is a malfunction, like a wire misfiring or a system throwing errors, then silencing it is a repair.
But pain is not a malfunction. It is a message. It is a system reporting that something in your body needs attention. Hiding the report does not change what is being reported.
And when a system silences the messenger without ever asking what the message means, you do not get healed. You get booked for the next procedure. That is how symptom masking works. Each treatment buys some time. The time runs out. And running out becomes the reason for the next treatment. It is a loop that is stable, billable, and repeatable. That is exactly why it lasts.
None of this blames the physicians doing these procedures. It is a point about what the model is built to do. A system built around procedures will reliably produce procedures.
Is the problem on my MRI really causing my pain?
There is a second built-in problem, and it sits before the shots.
In spine pain, imaging is famously unreliable at finding the pain source. That spot on your MRI, the bulge or the wear that was circled and explained to you, does not reliably explain what you feel. Plenty of people who feel just fine have one too. They have never had a symptom and never will.
This sets a trap with three steps. A structural finding is spotted. It is assumed to be the cause. A treatment is aimed at it.
When the treatment does not bring lasting relief, the usual conclusion is that the wrong level was targeted, or that a bigger procedure is needed. The conclusion is rarely that the finding was never the pain source at all. So the chase goes on, aimed at a target that may have been a side note all along. Meanwhile, the real driver goes unchecked.
What is really behind the pain signal?
Drawing on Hotamisligil’s landmark 2006 work on meta-inflammation, Dr. Padda connects a piece the assembly line does not: your pain signal is often downstream of a systemic metabolic fire that nobody measured.
That changes the whole picture. If the signal comes from an inflamed, metabolically unhealthy body, then the spot on your scan is not the source. And the local block is aimed at the wrong level of the problem entirely. Silencing the alarm does not put out the fire. It just means you find out about the fire later, and in a worse way.
It also explains something you have likely lived through: shrinking returns. The first block worked well, the second less so, the third barely. That is what you would expect from a local treatment aimed at a whole-body driver. The driver keeps sending signal, and the local block keeps falling behind.
Dr. Padda has spent more than thirty years across anesthesia, interventional pain, and metabolic health. He also owns clinics. That is why the critique here is specific, not vague. He knows exactly why the assembly line is built the way it is, because he has worked inside the same economics.
What is the next step if epidural injections don’t work?
The answer is not to reject needles. It is to change what the needle is for and when it comes.
At Regen.MD, the needle is not the therapy. It is the last, local step in a much bigger biological plan. The steps run in a set order: first we audit, then we restore the terrain, then we intervene.
The audit answers the question imaging cannot. What is really sending this signal, and what whole-body conditions keep it going? Restoring the terrain treats the metabolic and inflammatory setting before anything local is tried. Only then does a targeted treatment make sense, because only then does it land in a system that can respond to it.
If you have had a string of blocks with fading results, the useful next question is not which level to inject next. It is whether anyone has measured the fire.
Frequently asked questions
Are epidurals and nerve blocks always the wrong choice?
No. These are real tools with real uses, and sometimes blocking a signal is exactly the right thing to do. The concern here is about one pattern. It is repeated signal-blocking as an ongoing plan, aimed at a scan finding that may not be the pain source, while the whole-body driver is never checked.
Should I cancel my scheduled injection?
No. Do not start, stop, or change any treatment without consulting your physician. If this article raises questions for you, bring them to the physician who knows your case, or seek a formal second evaluation before your date. Nothing here is a directive to abandon care that has been recommended to you.
My MRI showed a real abnormality. Does this mean it is irrelevant?
Not necessarily. It means the finding cannot be assumed to be the cause without more proof. Imaging is unreliable at finding the pain source in spine pain, and people with no symptoms often have similar findings. Proving whether your finding causes your pain takes a match with your exam and history, not the image alone.
Why do the blocks work less well each time?
That pattern fits a local treatment aimed at a whole-body problem. If the driver underneath goes untreated, each round of local blocking fights an input that has not let up. It is a reason to widen the search, not to repeat the same approach harder.
Why do doctors keep recommending more injections?
Because the model is built around procedures, and a system built around procedures reliably produces procedures. Each shot buys some time. The time runs out, and its end becomes the reason for the next one. That loop is stable, billable and repeatable. It is not a judgment about the physicians doing the work. Dr. Padda owns clinics himself and knows exactly why the assembly line is built this way.
Does Regen.MD still use injections?
Yes. The answer is not to reject needles. It is to change what the needle is for and when it comes. At Regen.MD the needle is not the therapy. It is the last, local step in a bigger plan. First we audit, then we restore the terrain, then we intervene. That way the shot lands in a system that can respond to it.
What does the audit look for before another injection?
It answers the question your imaging cannot. What is really sending the pain signal, and what whole-body conditions keep it going? That means looking at the metabolic and inflammatory setting, not just the finding circled on your MRI. If you have had a string of blocks with fading relief, the useful next question is not which level to inject next. It is whether anyone has measured the fire.
Key takeaways
- Epidurals, nerve blocks, and steroid shots work the same single way: they block the signal.
- Pain is a message. Silencing the messenger books the next procedure instead of fixing the problem.
- In spine pain, imaging is famously unreliable at finding the pain source. People with no symptoms often have the same findings.
- Drawing on Hotamisligil’s 2006 work on meta-inflammation, the pain signal is often downstream of an unmeasured, whole-body metabolic fire.
- At Regen.MD the needle is the last step, not the therapy: audit first, restore the terrain, then intervene.
