Ultrasound-Guided Stellate Ganglion Block for the Treatment of Chronic Migraine in Adults: Study Protocol for a Randomized, Open-Label, Blinded Endpoint Trial

This study is a randomized controlled trial with a relatively large sample size to demonstrate the potential benefits of combined SGBs and drug therapy for CM patients. In the short term, this combined therapy will likely optimize CM treatment management. Further research will be needed to assess the efficacy of this treatment as a long-term therapeutic option.
