Summary
This study evaluates the efficacy and safety of ultrasound-guided stellate ganglion block (SGB) as an adjunctive treatment for patients with treatment-resistant fibromyalgia. Patients who continue to experience significant symptoms despite stable duloxetine therapy (60 mg/day) were randomized to receive either ultrasound-guided SGB or a sham control procedure. The study aims to determine if SGB can provide clinically meaningful improvements in fibromyalgia impact and pain intensity compared to a sham injection.
