NCT ID NCT07564362
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether injecting a dextrose (sugar) solution into the ligaments around the tailbone can reduce pain and improve daily function in people with long-lasting coccydynia (tailbone pain). Researchers reviewed records of 50 adults who received 3-6 injections over several weeks. The goal was to see if this simple, low-cost treatment helps when standard therapies fail.
