This is not normal.. continuous migraine for a month and a half?. If anyone can see you sooner, GO. You have explained to your Dr. that you are sick with the pain?
If no one can, and since you have tests, you might want to go to the ER. Have all test info in hand. May want to talk to your Dr. b4 doing that.. but this doesn't sound like something to fool with.
Getting in a "system" like health care can be real annoying.
do take care of yourself no matter what.
And BTW I would be venting too.
