What PNS may treat
PNS may be an option for chronic pain from a particular nerve or region, such as pain after a nerve injury or surgery, and some types of chronic low back, shoulder, or knee pain. Your provider will discuss whether your pain pattern is a good fit.
How it works
Using ultrasound or X-ray guidance, a very thin lead is placed near the target nerve through a needle. The lead connects to a small wearable or implanted stimulator that sends mild electrical pulses to interrupt pain signals.
Some PNS systems are designed for temporary use — the lead stays in place for a set treatment period (up to about 60 days for some devices) and is then removed. Other systems are implanted for long-term use. Some patients are offered a short trial first.
For focused nerve pain in the leg, foot, or groin, dorsal root ganglion (DRG) stimulation is another targeted neuromodulation option.
What to expect
- Placement is a minimally invasive outpatient procedure, usually with local anesthetic.
- You will learn how to use and adjust the stimulator.
- Keep the lead site clean and dry and follow the device instructions.
Risks
Possible risks include skin irritation from the dressing, infection, lead movement or breakage, and the stimulation not giving enough relief. We will talk through these before treatment.
Exercises you can do at home
Staying active is an important part of most pain treatment plans. See our low back (lumbar) exercises, shoulder exercises, and knee exercises for gentle stretches and strengthening options in lying, seated, and standing positions. Please ask your provider before starting, especially after a procedure.

Your provider will discuss whether this option is appropriate for you, along with its benefits, risks, and alternatives. Insurance coverage varies by plan — please call to verify.
