immese pain now....

Just recieved a late night (latenight where we are) call from my girlfriend.
She is having an immense kidney (maybe gallstone) attack.
She had had several a year ago but it had dissipated until yesterday.
She is not able to even see the doctor until tommorrow.

My questions are these.... first she had asked me several times about doing a flush but never did... well, shes asking me about it again!!!
Is it wise to do a flush while in so much pain or should she wait until it passes again?

Also, is there anything she can do tonite to help alleviate her pain?

I am thinking (altho could very well be wrong) that a strong flush (1 cp of oil and lemon) may not be the best idea when she is in this much pain... but I also saw a recipe that was slower and gentler, an oz of oil and lemon over several days... would this be better for her?

Also, does anyone know about the puree pear cure? I read it on another site but am wondering about its success...

Thanks all so much in this matter.....
