My adult daughter is considered in the top 2% of horrible migraine patients. She has been medicated like crazy, spent $10,000 (not insurance covered) on surgery and then tried the botox with very little other meds. This has been a game changer for her. She is thrilled! She still has mild migraines but not debilitating as they were before. I only posted this because like all treatments, sometimes it is horrible and sometimes it is the thing that changes your life for the better.
