ny times article - migraines

[Guest guest]

Curious if any of you understand this sentence from today's article about

migraines... [http://www.nytimes.com/2010/01/30/health/30patient.html?em]

" At your first visit, the doctor will make sure that your headaches are not

caused by an underlying illness, like Lyme disease or a brain tumor. "

I've been to top pain specialists in LA and DC and elsewhere for migraine over

the past 12 years. None of them ever mentioned Lyme (and none of their

suggestions gave me relief, btw). How do these doctors rule out Lyme?
