Hot pepper patch targets stubborn tailbone pain
NCT ID NCT05983263
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a high-dose capsaicin patch (made from chili pepper extract) can relieve long-lasting tailbone pain that hasn't responded to other treatments. Researchers will review medical records from 106 patients treated over six years to see how well the patch works and whether certain nerve-related symptoms can predict a good response. The goal is to find a new way to manage this often-hard-to-treat pain.
