Oh mummy Pam, i am so sorry to hear that!!
I never had that bad headhaches and for that long but i had enough migraines to know how much it is a pain! I also did MRI cos of this, but fortunately they turned up ok. I hope they can find the reason of your headhaches on the 3rd, and hope it is nothing serious. Keep us updated & take care of yourself.
Thinking of you
