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.
