How POSP Helps After a C-Section
POSP uses a technique called Percutaneous Nerve Field Stimulation (PNFS).
A trained healthcare provider places three small leads (thin needles) in strategic locations around your ear.
These leads connect to a small stimulator that is pre-programmed to send gentle electrical impulses that target nerve branches to reduce the pain messages traveling from your incision to your brain.
Many patients notice improvement within the first hour of wearing it.
Most people describe the sensation as mild or barely noticeable, and many stop feeling it altogether after a short time — but the device continues to work in the background.
POSP is an FDA-cleared, wearable nerve stimulation device designed to relieve post-operative pain following Cesarean delivery. Placed behind the ear, it sends gentle pulses over three days to reduce discomfort—no medications, no systemic side effects, and no added addiction risk.
