pain in the head !

My 7year old daughter suffers from the worst mirgraines i have ever seen for as long as i can remember and this is coming from a long time suffer myself. it was only this year after diet elimation and any other little thing i could think of to help for our doctor ( may i add a temp) to recgonise the extent of pain she is going through and we were sent to the hospital where we have gone through bloods cat scans mri's the works to no avail thus far other than morphine which she disgusts after i have had to grind them to mush and pretty mush pour down here throat along with the usual quite black and i mean blacked out room which to be honest is not always possile ! i was wondering if anyone else has the same problems with either their kids or themselves who maybe have some other ideas or anything to be honest to try help her in anyway. my greatest thanks to anyone who can help from both of us x
