To answer your Question= YES !
Not trying to scare you, but I stuggled with migraines for 3 years, all sorts of medications, some worked, some didn't. One day my wife insisted to me that I go to another Dr. because the current one insisted on treating me his self, and wouldn't do any thing but change medications, So....... I agreed and changed Dr's and was immediately sent to a neurologist for further examination.
Sadly I was diagnosed with a Menningiomas brain tumor, which was removed on Sept 8, 2006. So far so good, I have some problems, but I am ALIVE. So you see my opinion from my standpoint. I wasted 3+ years of my life, when it could have been taken care of earlier. Who knows if it would have mattered, but struggling with migraines for 3 years wasn't to pleasent either.....
Good Luck either way,
