For decades, chronic pain that didn't respond to conservative care left patients with two difficult options: long-term opioids or major surgery. Peripheral nerve stimulation offers a third path — a targeted, minimally invasive way to quiet a painful nerve at its source, without dulling the whole body.
I've now performed more than 600 peripheral nerve stimulation (PNS) implants, both temporary and permanent, across a wide range of pain conditions. In that time, few therapies have changed my conversations with patients as much as this one. PNS lets us treat the specific nerve carrying a pain signal — the knee, the shoulder, the low back, an amputation site — rather than asking the patient to take a medication that affects every system in the body.
What is peripheral nerve stimulation?
PNS is a form of neuromodulation: instead of removing or numbing tissue, it uses tiny electrical pulses to change how a nerve communicates pain to the brain. A thin lead, about the width of a few hairs, is placed near the targeted peripheral nerve under image guidance. That lead delivers gentle stimulation that the nervous system interprets as a soothing sensation in place of pain — a modern application of the long-studied "gate control" theory of pain.
Because the lead is positioned precisely next to the nerve responsible for a patient's pain, PNS can provide relief that is focused, drug-free, and reversible. There is nothing to swallow, no general anesthesia, and — for most patients — no overnight hospital stay.
Two approaches: 60-day temporary vs. permanent PNS
One of the things patients appreciate most is that PNS can begin with a low-commitment trial.
Temporary (60-day) PNS
In a brief, office-based procedure, a lead is placed near the nerve and connected to a small external stimulator worn on the skin. Over roughly 60 days, the system delivers therapy and is then removed. For many patients, the benefit outlasts the treatment period itself — the goal is to "retrain" the pain pathway rather than to leave hardware behind permanently.
Permanent PNS
For patients with longstanding pain who respond well and want durable, ongoing control, a permanent system with an implanted lead and generator may be appropriate. The decision is always individualized, and a temporary trial often helps inform it.
PNS is opioid-sparing by design. For appropriately selected patients, it offers a way to reduce or avoid the risks of long-term medication while still addressing the underlying pain signal directly.
Which conditions can PNS treat?
PNS is remarkably versatile because almost any peripheral nerve can be targeted. In my practice and in the literature, it is used for pain such as:
- Chronic knee pain, including osteoarthritis and persistent pain after knee replacement
- Shoulder pain that has not responded to injections or therapy
- Low back and buttock pain, including pain in the cluneal nerve distribution
- Post-surgical and post-amputation pain, including phantom limb and residual limb pain
- Nerve entrapment and neuropathic pain in the limbs
- Occipital and certain headache-related pain
My own real-world retrospective reviews have examined outcomes after 60-day PNS for knee pain, shoulder pain, and pain in the cluneal nerve distribution — work I've presented to help define where this therapy fits best. As with any treatment, results vary from person to person, and careful patient selection is everything.
What to expect from the procedure
A temporary PNS placement is typically done in the office using ultrasound or fluoroscopic guidance to position the lead with precision. Most patients are awake, the procedure takes a relatively short time, and many return to normal activities quickly with simple aftercare. Because the technique is minimally invasive, it avoids the longer recovery associated with open surgery.
Before recommending PNS, I take time to confirm the source of a patient's pain — sometimes with diagnostic blocks or imaging — so that we are stimulating the right nerve for the right reason.
Is PNS right for you?
PNS tends to be considered when pain has persisted despite conservative measures such as physical therapy, medications, or injections, and when a specific peripheral nerve can be identified as the culprit. It is especially worth discussing for patients who want to avoid or reduce opioids or who are not candidates for — or wish to avoid — surgery.
The only way to know whether you're a candidate is a thorough evaluation. If you're living with chronic pain and feel out of options, a focused conversation about neuromodulation may open one.
