A Peripheral Nerve Stimulation (PNS) trial is a minimally invasive procedure where small electrical leads or wires are temporarily implanted—typically for 7-10 days, but in some cases, up to 60 days—to help manage chronic pain. Think of it as a ‘try before you buy’ approach to determine if this treatment is right for you. Here’s what you need to know before and after your procedure.

You should not eat for 8 hours before your procedure, but clear liquids are usually allowed up to 2 hours before. Eating an anti-inflammatory diet and prioritizing sleep can support healing. Certain nutritional supplements may help prepare your body for the procedure and promote recovery.

If you take blood thinners, follow your doctor’s instructions on when to stop them. Thoroughly clean the surgical site using a pre-surgical wash like Hibiclens® the night before and the morning of the procedure to reduce infection risk. Wear loose clothing and arrange for someone to drive you home.

After the procedure, keep the leads dry and do not remove the bandage unless directed. Avoid getting the bandages or device wet—a sponge bath is recommended instead of showering or soaking.

Avoid heavy lifting or repetitive motions for 4-6 weeks to prevent lead displacement. Monitor your pain levels and report any changes at your follow-up visit.

Expect bandages at the site of the stimulator, depending on its location. Supporting your recovery with a nutrient-rich, anti-inflammatory diet, staying hydrated, and prioritizing quality sleep will help your body heal and improve your trial experience.

By following these guidelines, you’re taking the right steps toward a successful trial. If you have any concerns, contact the medical team.
