You know you have a Chiari when...
That ONE day a week (Maybe) that you wake up WITHOUT a headache and you spend ALL DAY wondering WHEN IT'S GOING TO START!
I can relate to lots of these, love this one: You know you have chiari when you watch mystery diagnosis looking so that you can find the cause of your symptoms.
After you read others' symptoms you add it to your own list, because you realize "oh, I have (or had) that too!".
When you read this list, it's like brand new all over again.
After giving your medical history to any new nurse/doctor, the first comment is, "well.... you certainly are interesting!"
