Daughter feels very ill before going for a poo!

[Lje1983]

I need some help please. She has been to the doctors who say they have never heard of these symptoms before and at the moment are doing no further investigations.
My 7 year old daughter very often suffers very painful symptoms about 10 minutes or so before she has a bowel movement. She gets a bad headache, lower back ache, feels very sick and goes as pale as a ghost! The 1st time it happened she was crying hysterically because she was in so much pain I phoned 111, by the time the docs rang back she had been for a poo & the symptoms had pretty much gone. It has been happening for at least 6 months now, not all the time but often enough to notice it's a thing! She isn't constipated, and has a pretty regular pattern of normal poo's. It doesn't seem to be diet related either as we have done a food & pop diary!!
Has anyone else experienced this because she really does get very poorly when it happens & we don't know why!
Any advice will be greatly appreciated x

Maybe her blood pressure drops, would explain headache and pale colour...could be to do with straining or bearing down

@Badders123 thank you, I have looked up what you suggested and it's the closest thing I've found so far, I have given my gp the information and hope to get it investigated further! The other thing I have found that offers similar symptoms is 'abdominal migraine'
We shall see...
