Your Spine Is Starving - That's Why Your Sciatica Won't Let Go

If you've tried everything and the pain keeps coming back, there's a hidden reason almost no one explains - and a surgeon's take on the one thing that finally addresses it. Please read this short article before you book anything else.

My name is Dr James Anderson. I'm a surgeon — MBBS, FRACS — and for more than 23 years I've treated Australians living with some of the worst back pain you can imagine.

Sciatica. Herniated discs. Bulging discs. Lower back pain. Spinal stenosis. Over the years I've seen all of it, and operated on plenty of it.

Most of the people who end up in front of me have already been around the block — physiotherapy, cortisone injections, sometimes years of medication — and they're still in pain. From a bit of morning stiffness, all the way to a hot, electric pain that shoots down the leg the moment they sit, bend or stand.

Sciatica bad enough that sitting down hurts

Mendable lifestyle

If that sounds familiar, you're not imagining it, and you're not being dramatic. I've watched this condition quietly take over people's lives.

And for a long time, I couldn't fully explain why so many of my sciatica patients never truly got better — no matter what we threw at it. Until I started paying closer attention to one detail almost everyone overlooks.

The part of the story you're rarely told

Mendable

Here's the version everyone knows. Years of sitting, posture, daily load — the spine compresses, a disc bulges, it presses on the sciatic nerve, and pain radiates down the leg. That part is true.

But it leaves the most important question unanswered: if we know exactly what's pressing on the nerve, why hasn't your body dealt with it?

Why didn't physio fix it? Why did the cortisone wear off after a few weeks? Why has nothing given you relief that actually lasts?

Your disc almost certainly isn't ruined. It's starved.
Mendable

Think about what happens when you cut your hand. Blood rushes to the wound, and a few days later it's healed. That's not luck — that's blood doing its job. Blood carries the oxygen, the nutrients and the repair cells your body uses to mend almost everything: every cut, every bruise, every broken bone you've ever had.

But your spinal disc is the one major structure in your body that sits so deep it receives barely any blood supply at all. The vessels that reach everywhere else simply don't reach it.

So when a disc bulges and presses on the nerve, the repair process that fixes the rest of you can't get there. The bulge stays. The nerve stays pinched. The pain stays.

And in a ten-minute consult, there's rarely time to explain any of this. The system is set up to manage the pain or to operate — not to give the disc the one thing it's actually missing. That's not a conspiracy. It's just how it works. But it's exactly why so many people cycle through treatment after treatment and never get lasting relief.

Why nothing you've tried has worked

Once you see it through the lens of blood supply, it all makes sense:

Mendable
  • Physiotherapy strengthens the muscles around the disc — but it doesn't get circulation into the disc itself.

  • Cortisone injections calm the inflammation around the nerve — but they don't restore the disc's blood supply.

  • Painkillers mute the pain signal — but they do nothing for the disc.

  • Surgery trims away the piece of disc pressing on the nerve — but it doesn't restore circulation or help the disc recover.

None of them were ever designed to do the one thing the disc needed. None of them got blood flow to the disc.

Your disc isn't broken. It's been starving.

Here's where it gets interesting

Mendable

When the disc does finally get good circulation, something remarkable can happen.

The body can reabsorb the herniated portion and draw it back, away from the nerve — on its own, without surgery. It has a name: spontaneous disc resorption, and it's well documented in the medical literature.

In other words, your body has very likely been capable of settling this the whole time. It just never had the conditions to begin.

The catch is that the window doesn't stay open forever. The longer a nerve stays compressed, the harder things tend to get — which is why I'd rather people understand this sooner than later.

So how do you actually get blood flow to the disc?

That was my next question, and the honest answer is: it isn't simple, because four things are standing in the way at once.

  1. The disc is physically compressed - so the pathway in is closed.
  2. Circulation isn't being actively driven to the area.
  3. Inflammation is blocking what little blood does get through.
  4. The muscles either side of the spine are locked tight, squeezing down on the disc between every treatment.

Miss even one of these, and you're spinning your wheels. That's why a heat pack alone doesn't fix it. Why decompression alone doesn't fix it. Why massage alone doesn't fix it.

You need all four — at the same time.

The four therapies

Each barrier has a therapy used in clinics to address it:

Spinal decompression

Spinal decompression

Gently opens the space around the disc so circulation can finally reach it.

Heat therapy

Heat therapy

Drives blood flow into the area, carrying in the oxygen and nutrients the disc has been starved of.

Red & infrared light

Red & infrared light

Helps settle the inflammation that's been blocking circulation.

Vibration massage

Vibration massage

Releases the tight muscles that keep clamping down on the disc between sessions.

Each one is genuinely useful. The problem is that on its own, each only clears one barrier — and until now, getting all four has meant booking three different clinics and spending hundreds, sometimes thousands of dollars, over months of appointments.

That's the problem I wanted to solve. So I worked with the team at Mendable.

Introducing the Mendable 4-in-1 Therapy Belt

The Mendable 4-in-1 Therapy Belt is, as far as I'm aware, the first at-home device to bring all four of these therapies into a single 20-minute session — decompression, heat, red & infrared light, and vibration, working together in the right order.

We call the system QuadFlow Therapy. It took proper development and testing to take something that used to require thousands of dollars across multiple clinics and put it into one device you can use from your own lounge room.

How it works

Here's what a session feels like.

The moment you strap it on, the decompression eases the load off your lower back — like a clenched fist slowly opening after years of being shut tight. Then the heat spreads across the area and starts driving circulation into the disc. The red & infrared light goes to work on the inflammation that's been getting in the way. And the vibration massage loosens the tight muscles on either side of your spine.

Four therapies. One session. Twenty minutes.

You strap it on, press a button, and sit back — on the couch, in front of the telly, after work, while you get on with your evening. No appointments. No waiting rooms. No recovery time.

Most people who use it consistently tell us they notice meaningful relief and easier movement within the first few weeks. It's designed to support your body's own ability to settle the problem — not to mask it.

What Australians are saying

★★★★★
After nearly five years of lower back problems, I'd stopped expecting much from anything new. What surprised me most wasn't some overnight change - it was realising one morning I'd slept through the night without waking to reposition myself. I use it while watching the evening news and it's become part of my routine. My back still needs looking after, but everyday life feels far more manageable now.

I retired two years ago looking forward to travelling around Australia with my husband - instead, my back had other plans, and we couldn't get through a long drive without stopping every hour. After a couple of months sticking with this, I'm moving more freely and far more confident about getting out and about. We recently drove Adelaide to Victor Harbor and I actually enjoyed the trip.

What I like most is how simple it is - fifteen minutes on the couch with a cup of tea and that's it. I've tried physio exercises, stretches and all sorts of gadgets over the years, and this is one of the few I've actually kept using, because it fits into everyday life. I feel steadier getting out of bed and far more comfortable standing in the kitchen.

Picture this

Mendable
  • No more shifting around at the dinner table every couple of minutes.

  • No more lying awake at 2am trying to find a position that doesn't hurt.

  • No more dreading that first step out of bed in the morning.

  • No more feeling like your own body has put your life on hold.

That's what becomes possible when the disc finally gets what it's been missing. You don't just get a bit of relief — you start to get yourself back. And that's the whole point of the Mendable 4-in-1 Therapy Belt.

The best part? It takes about 20 minutes a day.

How do you get one - and what does it cost?

The first question is the trickier one, because these devices take real time and money to build, and we keep running low on stock. If you're reading this, there's a good chance we still have some available — otherwise this page would be down. I can't promise for how long.

When we worked out pricing, given everything inside it, several hundred dollars would have been fair. To put it in perspective: a single physiotherapy session in Australia can cost around A$90-110 out of pocket, a course of clinic-based spinal decompression runs into the hundreds over months, and if surgery is on the table you're often facing either a long wait in the public system or a significant gap fee privately.

So the recommended price of A$349.95 made sense.

But I didn't work with Mendable to build another expensive device only a handful of people could afford. I did it because I want every Australian battling this to have access to something that actually addresses the cause.

Here's what to do next

Tap the button below and it'll take you straight to our official website. Choose your option, enter your shipping details, and you're done. Most people order in a couple of minutes.

Whatever you do, try not to close this page thinking 'I'll come back later.' When stock is low, later has a habit of disappearing.

Remember — there's no risk

The only real risk here is staying where you are. I've spent more than 23 years treating this condition, and the people who turned it around all had one thing in common: at some point they stopped waiting and gave their body what it actually needed.

Left alone, a compressed nerve rarely sorts itself out. For some people the numbness spreads or the leg gets weaker over time. I'm not telling you this to frighten you — I'm telling you because I've seen how much easier this is to help earlier rather than later.

Picture your life a few weeks from now. Getting out of bed without bracing for it. Sitting through a meal without shifting around. Walking without waiting for the pain. Sleeping through the night. Feeling like yourself again.

Your disc probably isn't beyond repair. It's been starved. Give it the conditions it needs — and give yourself the chance to get back to your mornings, your garden, your walks.
