I am a mother of a 19-year old boy. He has gotten migraines since he was in 4th grade.after a year of no migraines they returned, but are different. Three weeks ago he got the aura and it has been stuck there ever since. I've brought him twice to the hospital for shots. Nothing helps. I want to get a cefaly but the dr won't respond to our request for a prescription--needed in the US. Would rather have the 3-speed sold in other countries. Anyone out there with access to one, please contact me.
