American surgeons in the operating room

At 2:47 in the morning, I found my wife on the bathroom floor.

She was curled in the fetal position, her whole body shaking.

Not crying. Sobbing.

The kind of raw, primal sound that makes your stomach drop.

She didn't hear me come in.

When she looked up, she wasn't crying. Sophie never cries.

She just asked me the one question I had no answer for.

"Robert. You've operated on thousands of backs. Why can't you stop my feet from burning?"

I'm a spine surgeon. Thirty-two years. Over three thousand operations, most of them at the Cleveland Clinic.

Fifty-two years married to this woman. And I had nothing to tell her.

That night I understood what thirty-two years in the operating room had hidden from me.

The exact protocol I'd handed thousands of patients, people just like you, had quietly failed the one person I loved most.

Not out of malice. By design.

I'm seventy years old. I'm retired. And I'm going to tell you anyway.

The Night Everything Changed

American surgeons in the operating room

Sophie had been sleeping in the guest room for nine months.

She told me it was my snoring. It wasn't.

It was the burning in her feet — like she was standing on hot coals — that woke her at three in the morning. Electrical shocks shooting up her legs. Numbness spreading like her limbs were passing out.

That Tuesday, I woke up because the bed was empty.

The next morning I called our son Daniel.

Daniel is fifty-two. He spent twenty-two years as a biomedical engineer, building heat and ultrasound equipment for physical therapy clinics.

He drove up that weekend with his laptop and a stack of research papers.

He spent three days at our kitchen table reading things I had never read closely in thirty-two years.

By Sunday, he had the answer.

The protocol I'd handed thousands of women like Sophie wasn't built to make them better. It was built to manage them while they waited.

Eighteen Months. $11,400. Eight Treatments.

For eighteen months, Sophie did everything the American system offers a woman in her late sixties with "idiopathic peripheral neuropathy."

If you're on this path right now, you'll recognize every single line.

The neurologist. Kept increasing her Gabapentin until she was a zombie. $400 a month for brain fog and weight gain.
The pain management doctor. Pumped her full of nerve blocks that lasted two weeks max. $2,000 a pop.
The specialist at the clinic. Ran $15,000 worth of tests to tell us what we already knew: "idiopathic peripheral neuropathy" — medical speak for "we have no clue."
Gabapentin. Foggy. Twenty-eight pounds heavier in four months. Asleep by 8 PM. And the feet still burned.
Lyrica. $600 a month. Made her dizzy. The burning was identical.
Cymbalta. For the depression from being in constant pain. More drugs for the side effects.
Supplements. Vitamin B12. Alpha-lipoic acid. Blood levels normal. No measurable difference.
The spinal cord stimulator. $50,000. Recovery time: 6-8 weeks. Success rate: 50%. Still needed medications.

In total, more than $11,400 in eighteen months.

She was worse, not better.

She'd stopped picking up our granddaughter Ava, because the weight set off the burning for the rest of the day.

She'd stopped driving to see her sister Carol in Columbus, ninety minutes she could no longer sit through.

And then her primary care doctor said the line every American with chronic pain dreads.

"Mrs. Hartwell, in the meantime, you just have to tough it out."

The Line They Use When They've Got Nothing Left

"The protocol for chronic neuropathy is a painkiller for the nerve, a stomach pill for the painkiller, and a $50,000 stimulator with a fifty percent chance it does nothing. We call it treatment. It's a time-management scheme."
Dr. Robert Hartwell, MD

For thirty-two years, I was part of that system.

I told hundreds of women like Sophie to tough it out. To wait. To get on the list.

Seventeen minutes per patient. The deep-heat machine bolted to the wall of the PT department, never sent home.

No insurance billing code for the one thing that might have helped.

If anyone has ever told you to tough it out, please understand: it's not your fault. The system hands out the wrong tools, in seventeen-minute slots.

The Question Nobody Asked Me in 32 Years

Daniel listened to every pill, every appointment, every gel. He wrote it all down.

Then he asked me the question no one had asked in three decades.

"Dad. Why does the PT clinic have a $14,000 machine that heats and vibrates the deep muscle, but the patient goes home with a paper sheet and a pill bottle?"

I didn't have a good answer.

So he spent three days finding one. The clinical guidelines. The meta-analyses in BMJ and The Lancet. The VA study on gabapentin.

And the research on heat, vibration, and red and near-infrared light I had simply never opened.

Then he showed me where that light research started. NASA.

20M+
Americans suffer from peripheral neuropathy, with up to 40% of cases potentially misdiagnosed spinal compression (NIH, 2024)
1 in 10
non-surgical neuropathy treatments actually reduce pain, per a 2025 BMJ review of 301 trials
~55%
of people with chronic nerve pain report serious sleep disturbances
1 in 3
adults on chronic gabapentin therapy develop cognitive fog, weight gain, or dependency
38%
of "neuropathy" patients actually had spinal nerve compression, proven by Johns Hopkins researchers in 2019

A pill has to clear your whole stomach and bloodstream before a fraction reaches a nerve root two to three inches deep. The blood looks fine. The nerve is still starving.

Why the Burning Wakes You at 3 AM

Thermography: nerve inflammation

Here's the mechanism, in plain English, that no seventeen-minute appointment will ever explain to you.

Neuropathy was never one problem. It's four. And they feed each other in a loop.

One. A deep muscle in your lower back, buried beneath the gluteal tissue, wraps the nerve root like a noose and locks into spasm.

Two. That locked muscle clamps the nerve and chokes off its own blood supply.

Three. With the blood goes the oxygen, and inflammatory waste gets trapped against the nerve.

Four. Starved of oxygen, the cells in that nerve run out of energy and can't repair, so the nerve never stops firing.

And then it starts again. Worse every year.

That's the burning in your feet at three in the morning.

That's the electric shock when you stand up off the couch.

It's the dead, wooden leg when you wake up.

"Nerve blocks numb the signal. That's one side of the loop. They never touch the locked muscle, the cut-off circulation, or the drained cells that keep the nerve firing. That's why the burning always comes back."
Dr. Robert Hartwell, MD

What Daniel Laid Out on the Kitchen Table

The Revornyn ThermaPro prototype on the kitchen table

So how do you get into a loop the needle only touches one side of?

Daniel started with the fourth problem: the drained cells.

Inside every nerve cell are tiny engines called mitochondria. They make the energy your body repairs itself with, called ATP. Think of it as a battery.

Years of being squeezed run that battery flat.

A drained nerve cell isn't broken. It just has no power left to calm the inflammation or quiet the signal.

That's why no pill ever reached it. You can't recharge a battery by swallowing one.

Picture a flower shut in a dark room. It wilts. Not because it's dying, but because a flower lives on light, and none is reaching it.

Move it to the window, and it comes back to life. Your nerve cells are no different.

This is where NASA comes in. When they needed to keep astronauts' cells alive and repairing in space, they found that a certain red and near-infrared light, absorbed inside the cell, switches that energy back on.

The clinics already had a $14,000 machine that combined that light with deep heat and vibration. The patient just never got to take it home.

Three technologies, working the loop at the same time.

Deep heat drives blood and oxygen back into the locked muscle, two to three inches down, and coaxes it to release.

Pulsing vibration breaks the spasm-pain cycle and pumps out the trapped inflammatory waste. No stomach. No pills.

Red and near-infrared light recharges the drained nerve cells, the NASA effect, and helps the nerve finally calm down.

Heat and vibration reach the deep muscle. The light recharges the cells that ran out of power.

Nerve blocks reached one side of the loop. These three break all four.

Daniel strapped the prototype on Sophie's lower back on a Friday night in November.

She rolled her eyes. She'd already tried Voltaren, Tiger Balm, a copper sleeve, and a drugstore heating pad that warmed her skin and nothing underneath.

She agreed because Daniel had driven up two weekends in a row.

Sophie's Recovery, Week by Week

Margaret back on her feet
Week 1

One fifteen-minute session before bed. Warmth, then the deep pulse, then the red glow against her skin. She slept four hours straight without her feet waking her. First time in eighteen months. She put it on again after breakfast without me asking.

Week 3

She dropped her evening Gabapentin, then her afternoon dose. Within ten days she'd cut her nerve medication by more than half. The burning was down to a simmer.

Week 6

She walked the dog twice around the block. The following Saturday she rode ninety minutes to her sister Carol in Columbus without pulling over once. "I could feel the pedals," she said.

Month 3

Our granddaughter Ava came for the weekend. Sophie pushed her on the swing for twenty minutes. Then she sat on the couch and cried for ten minutes straight. Not because it hurt. Because she'd gotten her life back.

Fifty-two years married. I'd never seen her cry like that.

From One Kitchen to 23,000 Customers

Walter back at Lake Erie

In a small Ohio town, word travels at the speed of the morning dog walk.

Walter, 73. Retired mail carrier. Six years of Lyrica, a wrecked stomach, and three fishing trips to Lake Erie he'd cancelled. Six weeks with the belt, and in May he drove up and caught a walleye. "I could feel my toes in the water," he said.

Paula, 68. Retired charge nurse, thirty-one years in the orthopedic unit. She'd handed out this exact protocol for three decades, then needed it herself. Off Gabapentin and tramadol in two months.

A neighbor's mother, 71. Sixteen months on a spinal stimulator waiting list. Three months on the belt, and her pain management doctor agreed to monitor her instead of operating. She's still off the schedule.

Daniel and I registered a small company, Revornyn Health.

We named the device Revornyn ThermaPro, after what Sophie said the first time she felt it sink past her skin:

"It's like the blood is coming back to a place it stopped reaching."

Then the Letters Started Coming

Walter back at Lake Erie

In eighteen months, we received over nine hundred letters from all over the country.

Husbands writing for their wives. Daughters writing for their fathers.

The pattern was the same in every state. Years of Gabapentin. Lyrica added. A photocopied PT sheet. A nerve block or two that lasted less each time. A pain-clinic appointment eight to fourteen months out.

"For the last eighteen months I told my daughter I was fine because she already has enough to worry about. I'm writing to tell you I've stopped saying it. I can feel my feet again."

Tens of thousands are quietly stepping off the pills-and-injections conveyor belt every year.

Not by paying for a stimulator. By reaching the loop around the nerve directly, fifteen minutes a day, in their own chair.

So Let Me Show You Exactly What It Does

My son engineered it in the USA, around the same three mechanisms the clinics charge $14,000 a machine for.

Three technologies, working the loop at once, in one cordless belt. Once a day. Fifteen minutes.

Technology How It Works on the Loop
Tech 1
Deep Heat
Targeted Thermal Therapy (up to 150°F, adjustable). Drives warmth and blood flow two to three inches into the deep muscle, the same principle as the heating units in PT clinics. The contracted muscle relaxes its grip on the nerve root.
Tech 2
Massage
Pulsing Vibration Massage (multiple modes). Mechanically breaks the spasm-pain-spasm cycle and pumps the stagnant tissue, flushing the inflammatory waste trapped against the nerve. No pills, no stomach damage.
Tech 3
Red Light
Red & Near-Infrared Light (photobiomodulation). The same effect NASA used to keep cells alive and repairing in space. It recharges the drained nerve cells around the compressed root and helps calm the irritated nerve endings as the muscle lets go.

You sit down, strap the cordless belt around your lower back, press the button, and pick your heat and massage level.

Fifteen minutes. Then you take it off and go on with your day. No wires, no pills, no appointment.

How It Works: 3 Steps, 15 Minutes

1
Step 1: strap on the belt
Strap It On
Wrap the cordless belt around your lower back, right over where the nerve root gets strangled. Adjusts to any waist.
2
Step 2: pick heat and massage level
Press & Set
One button powers it on. Deep heat, pulsing massage, and red and near-infrared light switch on together.
3
Step 3: relax for 15 minutes
Sit Back
Relax in your own chair while heat and vibration reach the deep muscle and the light recharges the nerve cells. Then go on with your day.
Just 15 min / day

Let's Do the Math Honestly

Let me ask you something I can ask after thirty-two years in spine medicine.

How much have you spent in five years on feet that are no better than they were?

Treatment Typical Annual Cost What It Actually Does
Gabapentin / Lyrica $350–2,160 Foggy. Heavier. Still burning.
Cymbalta $350–420 Masks the mood. Nerve still screaming.
Nerve blocks $2,000–8,000 2 weeks of relief. Then nothing.
Specialist tests $3,000–15,000 Tells you what you already know.
Spinal cord stimulator $50,000 50% success. Still on meds.
Supplements (B12, ALA) $200–400 Blood levels fine. Cells still starving.
Typical 5-year total $15,000–80,000 And usually a wrecked stomach.
Revornyn ThermaPro $99 once Reaches the loop directly. Use it for years.

The ThermaPro is a one-time $99. Not $99 a month. Once.

Less than a single nerve block. And it never burns your stomach.

American veteran at home

If you're a veteran, you know this part already.

The VA handed you gabapentin and a shrug. The burning has run down your legs every night since.

About half the people who write to us are veterans.

The loop is the same whatever set it off: a locked muscle, a strangled nerve, cut-off circulation, drained cells.

It's drug-free. Nothing that interacts with your VA medications. You strap it on for fifteen minutes a day, and the heat, vibration, and red and near-infrared light do the work.

90 Days, Zero Risk

The "Nerve Free or Refunded" Guarantee: 90 Days + 1-Year Warranty

I know what you're thinking. You've heard it a thousand times.

"I've tried other things. They all promised the world. Why is this one different?"

Here's our answer. Use the ThermaPro for ninety days, fifteen minutes a day. If you don't sleep better, walk better, or feel your feet again, send us one line by email: "It didn't work."

A note from me, because I'm a surgeon first. Some people genuinely need a spinal cord stimulator or surgery. If you've lost control of your bladder or your foot drags when you walk, that is beyond what this device addresses: see a doctor now. The ThermaPro is not a diagnosis or a substitute for surgical judgment. Always talk to your own doctor before changing any medication, especially gabapentin or Lyrica, which need a gradual taper.

Frequently Asked Questions

Does it work if my neurologist confirmed peripheral neuropathy?
Yes. A confirmed neuropathy diagnosis is exactly the stage where the deep muscle around the nerve root is most locked, and where heat, vibration, and red and near-infrared light have the most to work on. Most of our customers come to us with a confirmed diagnosis that hasn't responded to medication. Johns Hopkins research showed 38% of "neuropathy" patients actually had spinal nerve compression.
Can I use it if I'm on a waiting list for a spinal cord stimulator?
Yes. Many customers use it during the long wait. Some find the pain reduction is enough to come off the list. Others use it to keep the nerve calm until their date. Always inform your pain management specialist.
My B12 levels are normal. Why would this be different?
A pill spreads through your whole bloodstream and barely any reaches a deep, starved nerve root. The blood is fine. The cells are not. The ThermaPro skips the bloodstream: heat and vibration reach the muscle two to three inches down, and the red and near-infrared light recharges the drained nerve cells directly, the same effect NASA documented in tissue repair.
Will it help me get off Gabapentin, Lyrica, or Cymbalta?
It addresses the muscular and circulatory cause at the source, which for most users reduces the need for daily nerve medication. Many come off NSAIDs and the medications protecting their stomach. Always consult your doctor before stopping any prescribed medication, especially gabapentin or Lyrica, which need a gradual taper.
Is it suitable for adults in their seventies and eighties?
Yes. Most of our customers are between sixty-five and seventy-eight. The oldest who has written to us is eighty-six. It's drug-free, with adjustable heat and massage levels, and does not interact with prescription medication.
Can I buy it for my husband, wife, or a parent?
Yes. About thirty percent of our orders come from spouses and adult children buying for a family member. The belt is adjustable and suits any adult with chronic nerve pain or "neuropathy" symptoms.
How long before I feel something?
You feel the warmth and the massage from the first session. The deeper muscle release builds over the first one to two weeks. Most customers report better sleep within the first month and a clear change in burning and numbness within six weeks.
What if it doesn't work for me?
You have 90 days from delivery to return it for a full refund. One email, "It didn't work," and your money is returned in full. Every unit is also covered by a 1-year warranty.
