DRG Stimulation
What it is
DRG stimulation targets a small bundle of nerves near the spine. A small device sends mild signals to these nerves. It may help pain in one area, such as the foot, knee or groin.
Why it is done
- Complex regional pain syndrome (CRPS) types I and II in the lower limbs
- Focal chronic nerve pain in the groin, knee or foot
- Pain that has not responded to other treatments
What to expect
- Before: You try the device first for about a week. Thin wires are placed through a needle and connected to a small device you wear outside the body.
- During: You and your doctor look at how much your pain and daily activities improved during the trial.
- After: If the trial helped, a long-term device is placed under the skin in an outpatient procedure. You will have follow-up visits to adjust the settings.
Self-care tips
- Keep the cut clean and dry until it heals.
- During healing, avoid bending, lifting and twisting as told.
- Carry your device ID card. Tell other providers you have a device before any MRI.
- Charge or check your device as shown.
When to call us
- Fever over 101°F or chills
- Redness, swelling or fluid draining from the cut
- The device stops working or gives an unusual feeling
- Symptoms that get worse
