Peripheral Nerve Stimulation
Peripheral nerve stimulation is a targeted neuromodulation option for selected focal nerve pain conditions, using electrical stimulation near a peripheral nerve to reduce pain.
Pain and neuromodulation pathway
From pain mapping to durable management
Goals
Clarify pain relief, function, sleep, medication burden, and quality-of-life priorities.
Mapping
Identify whether symptoms follow a nerve, spinal pathway, facial pain syndrome, or broader pain pattern.
Treatment review
Review therapy, medications, injections, blocks, surgery, imaging, and prior response.
Option selection
Choose stimulation, intrathecal pain therapy, lesioning, nerve surgery, or continued non-surgical care.
Trial or procedure
Use trials when appropriate, or proceed with the selected targeted treatment plan.
Long-term care
Adjust programming, dosing, refills, precautions, and follow-up over time.
Goal-directed care
Treatment planning starts with pain relief, function, sleep, medication burden, and quality-of-life goals.
Selective options
Surgery is considered when medication, therapy, injections, or conservative care are not enough.
Adjustable follow-up
Stimulation and pump therapies require ongoing management to keep treatment aligned with goals.
Overview
Peripheral nerve stimulation (PNS) targets pain closer to the injured or irritated nerve. It can be useful for selected patients whose pain follows a specific peripheral nerve distribution.
PNS is a form of neuromodulation. It uses mild electrical stimulation near a peripheral nerve to change the pain signal before it travels through the spinal cord and brain. It may reduce pain enough to improve function, but it does not necessarily remove all pain or repair the original nerve injury.
When it may be considered
PNS may be considered when pain is focal, neuropathic, and persistent despite medication, therapy, injections, or prior procedures. It is not a general treatment for all pain; the pain source must be targetable.
How it works
An electrode is placed near the affected nerve and connected to a stimulation system. Stimulation settings are adjusted to reduce pain while preserving function.
Some systems use a temporary external generator, while others use an implanted generator. A temporary trial or temporary treatment period may be used first to determine whether stimulation meaningfully improves pain and daily activity before a permanent implant is considered.
Conditions sometimes evaluated
- Focal nerve injury pain
- Occipital neuralgia and selected headache-related nerve pain
- Post-surgical neuropathic pain
- Selected limb pain syndromes
What to expect
- Careful mapping of the painful area to a targetable nerve
- Review of prior treatments, nerve blocks, imaging, and nerve studies when relevant
- Discussion of temporary stimulation, trial goals, and what counts as meaningful benefit
- Programming adjustments to balance pain relief, sensation, and activity
- Device education, activity restrictions, and follow-up if a system is implanted
Risks and limitations
Risks can include infection, bleeding, lead movement or breakage, uncomfortable stimulation, increased pain, nerve irritation, and device-related limitations with some imaging or procedures. PNS works best as part of a broader plan that may include therapy, medication optimization, and treatment of the underlying nerve problem when possible.

Frequently asked questions
What is peripheral nerve stimulation? +
Peripheral nerve stimulation uses a small electrode placed near a painful nerve to modulate pain signals. It may be temporary or implanted depending on the system and indication.
What types of pain may it help? +
It may help selected focal neuropathic pain conditions, including pain after nerve injury, surgery, entrapment, or certain headache and limb pain syndromes.
How is candidacy determined? +
Candidacy depends on whether the pain maps to a targetable nerve, prior treatment response, imaging or diagnostic studies, and sometimes response to nerve blocks.
