What this trial studies
This trial evaluates the effectiveness and safety of two treatments for chronic migraine: sphenopalatine ganglion block (SPGB) and intramuscular BOTOX injections. Chronic migraine is characterized by headaches occurring 15 or more days per month, with specific criteria for migraine episodes. The study aims to determine which treatment provides better relief for patients suffering from this debilitating condition. Participants will be monitored for their response to each intervention over a defined period.
Why it matters
Potential benefit: If successful, this study could provide a more effective treatment option for patients suffering from chronic migraines.
How similar studies have gone: Previous studies have shown promising results for both sphenopalatine blocks and BOTOX in treating chronic migraines, indicating that this approach is supported by existing evidence.
