I have not, thank God, experienced migraines that go to this extent. But I have had a few that dropped me to my knees.
When stuff like this happens, it's really hard to explain it to a doctor, isn't it? If it ever happens to you when a friend or family member is around, DRAG that person to the doctor with you at your next appointment! Some doctors seem to need proof!
I know how frustrating it is to switch doctors. And it's so true that the doctor gets frustrated when (s)he can't figure out what to do next. A GOOD doctor will refer you to someone smarter!
I posted this somewhere else.
Remember, 50% of all the doctors out there graduated in the bottom half of their class!
Some doctors are not as smart as you need them to be.
