This study is looking at whether a nerve block combined with oral dexamethasone (a steroid medication) can help prevent migraine headaches from returning within 72 hours. You might be able to join if you are between 18 and 85 years old, have migraine headaches that meet specific criteria, and your headache pain significantly improved after a nerve block. The study will compare people who receive two 4mg pills of oral dexamethasone to those who receive two placebo pills (inactive pills). The main goal is to see if taking dexamethasone after a nerve block reduces how often headaches come back within 72-96 hours. The current recruitment status is unclear.
