Could a simple neck injection ease fibromyalgia pain?
NCT ID NCT07343128
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether an ultrasound-guided nerve block injection (stellate ganglion block) could help people with fibromyalgia who still have symptoms despite taking duloxetine. 68 adults received either the active injection or a sham (fake) injection, and researchers measured changes in pain and overall impact after one week and one month. The goal was to see if this procedure offers a safe and effective add-on treatment for hard-to-treat fibromyalgia.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- lidocaine and dexamethasone injection
- What this could lead to
- If it works, this could provide a new way to reduce pain and improve daily life for people with fibromyalgia who don't get enough relief from standard medications.
- What could go wrong
- This is a small, early-phase study with only 68 participants. The results may not apply to everyone, and the benefits might be short-lived or no better than a placebo.
