I get migraines all of the time. I wish I knew what caused them.

Yeah I've also heard that they can be caused by stress.
Thats a big factor too, they affect usually only one side of your head but they are painful and pulsating
I know another thing that seems to disinghish them from headaches is that the pain sometimes migrates. Hence the name!
