NCT ID NCT07280780
First seen Jun 27, 2026 · Last updated Aug 13, 2026 · Updated 2 times
Summary
This study tracks blood sugar changes after an epidural steroid injection for back or leg pain. Researchers will compare 36 adults with and without type 2 diabetes using a continuous glucose monitor worn for 15 days. The goal is to see if the injection causes higher or longer-lasting glucose spikes in diabetic patients. Participants receive one injection and visit the clinic three times.
