“The Tingling Moved and the Pain Came Back”: Spinal Cord Stimulator Lead Migration
Summary
A spinal cord stimulator uses thin wires, called leads, placed near the spinal cord. If a lead moves, the stimulation can shift away from where you need it and the pain relief can fade. This guide is for people whose stimulator stopped working, needed repeated reprogramming or more surgery, or who now wonder whether they should have had it at all. It explains lead migration, the warning signs, and when it might point to care that fell short.
Quick answer · updated November 2026
Lead migration is one of the most common reasons a spinal cord stimulator stops helping. Typical signs are pain relief fading, or the tingling moving to a different part of your body. If reprogramming doesn’t fix it, ask for an X-ray to check where the leads are. Australia’s medicines regulator reviewed these devices from 2022 and cancelled or put conditions on many of them.
Your stimulator at a glance
- 1Before the implantYou should be told the evidence, the risks and the revision rates.
- 2The trialA temporary trial usually comes first, to see if it helps.
- 3Permanent implantLeads are anchored to reduce movement. Early weeks matter most.
- 4Relief fadesReprogramming may help. If not, ask for imaging of the leads.
- 5Revision or removalFurther surgery is common. Ask why, and what the options are.
At any stage: a red, hot or weeping wound, fever, or new weakness, numbness, or bladder or bowel problems need same-day care. Go to an emergency department if you can’t reach your team.
I drove trucks for thirty years before my back gave out. After two operations and a lot of tablets, the stimulator trial felt like a miracle. For a week the pain down my left leg was replaced by a buzz, like a phone on silent in my pocket. I slept through the night for the first time in years.
The permanent one went in that winter. Three months later I bent to pick up the dog’s bowl and felt the buzz slide. Not in my leg anymore. Round my ribs, under my arm. The leg pain came back like it had never left.
At the clinic the technician plugged in a tablet and tried new settings. “We’ll just reprogram it, mate. They all need tweaking.” I went back four times. Each time I drove home with the buzz in the wrong place and the pain in the right one.
My wife asked me, “Has anyone actually looked to see where the wire is?” I didn’t know.

If you are reading this with a stimulator that no longer helps, or with a scar from a second or third operation, you are asking reasonable questions. Some people do very well with spinal cord stimulation. Others don’t, and the reasons are not always explained to them.
This guide is for anyone with a spinal cord stimulator, and for the partners who drive them to appointments. It covers what lead migration is, how it should be investigated, the warning signs, what the evidence and regulators say about these devices, what your records should show, and how the law looks at it.
Why I can write this
I have been a medical negligence lawyer since 2014 and have worked on many hundreds of claims, including many involving spinal surgery. My doctorate looked at patterns of failure in medical negligence. I am not medically qualified. The clinical facts in this article are checked against named sources, listed in the references, and I explain how I work in our editorial standards.
Start with your question
- What happens when spinal cord stimulator leads move?
- What are the symptoms of lead migration?
- Can reprogramming fix a lead that has moved?
- How common is revision surgery for a stimulator?
- When is it urgent?
- Do spinal cord stimulators actually work for back pain?
- Could this be medical negligence?
What a spinal cord stimulator is
Definition
A spinal cord stimulator is an implanted device that sends small electrical pulses to the spinal cord through thin wires called leads, placed in the epidural space along the spine. A battery, called the implantable pulse generator, sits under the skin, usually in the buttock or flank.
In plain terms: wires near your spinal cord, powered by a battery under your skin, try to change how pain signals reach your brain.
Leads come in two main kinds. Percutaneous leads are threaded in through a needle. Paddle leads are flatter and are placed through a small surgical opening. Which kind you have affects how likely the lead is to move.1
Before the implant
What the evidence says
Whether spinal cord stimulators work for back pain is contested. A 2025 commentary in the Medical Journal of Australia summarised two Cochrane reviews: one in 2021 found very low-certainty evidence that stimulation may not be better than placebo for pain, and one in 2023 on low back pain found moderate-certainty evidence that it probably isn’t better than placebo in the medium term.2 Some patients and clinicians report real benefit. Either way, you were entitled to hear about the uncertainty before deciding.
The trial
A temporary trial is usually done before a permanent implant, to see whether stimulation actually helps you. An Australian study discussed in the same commentary found that about a quarter of patients had a permanent device implanted without a trial first.2
Questions to ask before a permanent implant
- What does the evidence say for someone with my kind of pain?
- Will I have a trial first, and what counts as success?
- Which device and which type of lead, and why?
- How often do leads move, and what happens if mine does?
- How many people need further surgery or have the device removed?
- Is this device subject to any conditions from the TGA?
- Who will follow me up, and how often?
What lead migration is
Definition
Lead migration is when a stimulator lead moves from where it was placed, so that the electrical field no longer covers the painful area.
In plain terms: the wire has shifted, so the stimulation is now in the wrong place.
Lead migration is a well-recognised complication. A 2021 review of the literature reported migration rates of about 13 to 23 per cent with older generations of percutaneous leads, about 2 to 9 per cent needing revision with modern techniques and anchoring, and about 0 to 6 per cent with paddle leads.1 The same paper describes surgical steps used to reduce migration, including anchoring the lead to the tissue beneath the skin, leaving strain-relief loops, and placing the battery in a suitable position.1
The signs
The main sign is pain relief fading. With traditional stimulators, the tingling sensation may also move to a different part of the body, or change sharply when you change position.1 Some newer devices don’t produce tingling, so loss of relief may be the only clue.
Reprogramming, imaging and revision
Small movements can sometimes be managed by changing the stimulation settings. But when relief doesn’t return, the next step is to check where the leads actually are. In the 2021 study, patients without adequate relief at six months had their lead position checked on imaging, and leads were surgically revised if needed.1 Repeated reprogramming without anyone looking at the leads may delay a problem being found.
Expected, worth a review, or same-day help
A general guide only. Your treating team’s instructions come first.
Usually expected
- Wound soreness in the first weeks
- Getting used to the sensation
- Some adjustment of settings
- Restrictions on bending and lifting early on
In plain terms: a settling-in period.
Ask for a review
- Pain relief fading
- Tingling moved to a different area
- Jolts or shocks when you change position
- Reprogramming isn’t fixing it
- Pain or swelling over the battery
In plain terms: ask for the leads to be checked on imaging.
Same-day help
- Red, hot or weeping wound
- Fever or feeling unwell
- New weakness or numbness in the legs
- New bladder or bowel problems
In plain terms: get help today, or go to an emergency department.
How common is more surgery?
More common than many patients are told. The Medical Journal of Australia commentary noted an analysis based on regulator data of roughly four devices removed for every ten implanted, and an Australian study of 4,361 permanent implants in which 23.2 per cent of patients had at least one further operation, mostly within three years.2
If you are facing a revision or removal, ask what is being done and why, what the alternatives are, and what the chances are that it will help. Our guide to what to do if you still have pain after spinal surgery may also help.
If you were told repeatedly that nothing was wrong, see when being dismissed by a doctor becomes a legal issue.
The X-ray took five minutes. The pain specialist I was finally referred to put it next to the one from just after my operation and pointed with her pen. “That lead was here,” she said. “Now it’s here.” Two vertebrae higher. Not a small move.
When I got my records there was an X-ray from my six-week check. The report said the leads had moved up. Nobody had told me. After that came four programming sessions, all noted as “stimulation adjusted, patient reports partial relief”.
My wife read the report out loud in the kitchen, then read it again. “Six weeks,” she said. “They knew at six weeks.”
I had the revision. It’s too early to say if it’s worked. But for the first time, I know exactly what happened to me and why.

What to look for in the records
Your records are often where the story becomes clear. You have a right to access your own health information. In NSW the Health Records and Information Privacy Act 2002 covers both public and private providers, and the Information and Privacy Commission explains how to ask.3 Our step-by-step guide to getting your medical records in Australia walks you through it.
| Record | Why it matters |
|---|---|
| Assessment and consent before the trial and implant | Shows whether the evidence, risks, migration and revision rates were explained, and whether a trial was done. |
| Operation report | Records the device, lead type, where the leads were placed and how they were anchored. |
| Post-operative X-rays and reports | Show where the leads were at the start and whether that changed. Compare dates and positions. |
| Programming records | Show how often settings were changed and what was recorded about your relief. |
| Referral letters | Show whether, and when, anyone looked into why relief had faded. |
| Device details | The model and serial number. Some devices have since had TGA conditions imposed or been cancelled. |
| Your own diary, photos and messages | Notes made at the time are evidence too. Keep them. |
How the law looks at it
A lead that moves is not, on its own, negligence. Migration can happen even with careful technique. The legal questions are whether the care you received, from selection through to follow-up, met the standard expected, and whether any shortfall caused you harm.
A claim usually turns on three questions: whether the care fell below what peers would widely accept as competent practice (section 5O of the Civil Liability Act 2002 (NSW))4, whether that shortfall probably caused harm you wouldn't otherwise have had (Tabet v Gett)5, and, where it matters, whether you were told the material risks first (Rogers v Whitaker)67. Our guide to how a medical negligence claim works explains each one in plain terms.
In a stimulator case, the questions might be: were you a suitable candidate? Was a trial done? Were the leads anchored using accepted techniques? When your relief faded, were the leads checked on imaging, and was a problem acted on promptly? Was an X-ray showing movement followed up?
In plain terms, the question is whether better care would probably have avoided the extra surgery, the months of lost relief, or other harm you suffered. Problems with the device itself can raise separate questions about the manufacturer.
For a stimulator, that would usually include the uncertainty in the evidence, the chance of lead migration, infection and device problems, and how often people need further surgery or removal.
Who can claim, and when
The person who had the implant can claim. In NSW, time usually runs from when you knew, or ought to have known, enough to claim, not from the treatment itself, and courts can sometimes extend it, so an old injury may still count. See time limits in NSW or other states, and ask early.

In my practice
In stimulator files, I often see a pattern that starts with hope. The trial feels wonderful, the permanent device goes in, and then relief fades. What follows is often a series of programming visits, each noting “partial relief”, while the question of where the leads actually are goes unasked. Sometimes an early X-ray already showed movement, and the report sat in the file. Sometimes there was never a trial at all. Each step on its own can look reasonable, and the people involved may be doing their best. Together they can mean months of pain, a second operation, and a patient who blames himself for bending over to pick something up. Bending is part of life. Checking the leads is part of follow-up.
Both things can be true
Your stimulator may have helped you for a while, and the way problems were handled may still have fallen short. Your surgeon may be skilled, and you may still not have been told how often these devices need more surgery. You can be grateful for the relief you had and still want to know why it stopped.
The bigger picture
In 2022 the Therapeutic Goods Administration began a review of all spinal cord stimulators on the Australian Register of Therapeutic Goods, after increasing reports about their safety and performance. It has cancelled devices from some sponsors, including Medtronic Australasia in 2024, and imposed conditions on many others. The TGA says cancelled devices are not being recalled and implanted devices do not need to be removed because of the cancellation, and it encourages patients to report concerns.8
The Medical Journal of Australia commentary calls for better evidence before these devices are widely used.2 You can check your surgeon’s registration on the Ahpra public register,9 and complaints about care in NSW can go to the Health Care Complaints Commission.10 Device harms more generally are covered in our guide to medication, drug and device harm.

Frequently asked questions
What happens when spinal cord stimulator leads move?
The stimulation can shift away from the painful area, so pain relief fades or the tingling moves somewhere else.
What are the symptoms of spinal cord stimulator lead migration?
Loss of pain relief, tingling in a different place, or jolts when you change position.
Can lead migration be fixed with reprogramming?
Sometimes, for small movements. If relief doesn’t return, the leads should be checked on imaging and may need revision.
How common is revision surgery for spinal cord stimulators?
Common. One Australian study found nearly a quarter of patients had at least one further operation.
Has the TGA taken action on spinal cord stimulators?
Yes. Since a review began in 2022, the TGA has cancelled some devices and put conditions on many others.
Can I claim if my stimulator leads moved?
Possibly. It depends on whether your care fell below the accepted standard and caused harm you wouldn’t otherwise have had.
