Determine the effects of sphenopalatine ganglion (SPG) block in post-stroke headache.
The purpose of this study is to determine if sphenopalatine ganglion (SPG) block is a safe and effective treatment for acute post-stroke headache. Current literature lacks randomized controlled studies regarding the efficacy of different treatment modalities for acute post-stroke headache; additionally, there are no evidence-based guidelines for the treatment of acute post-stroke headache. Sphenopalatine ganglion block is a non-invasive procedure where an anesthetic agent is injected into the nares, reaching the SPG to relieve pain and autonomic features. This treatment has been effective in a variety of headache types but to our knowledge has not been studied in acute post-stroke headache.
