Joy in the hospital again-need advice

Hi everyone, I am very sorry to report that Joy is in the hospital again. She has been in so much pain that radiates from her lower abdomen to around her back and down her thighs. She was in so much pain yesterday morning and so out of it, I took her to the ER and then they admitted her to give her some pain control. They did a CBC which was normal, the liver panel isn't back yet, but on last Tuesday it was all good. She has a low grade fever so they are doing some cultures. They will do an ultrasound today to see if she needs to be tapped again. But she's not looking too distented. I was wondering if any of you wonderful people have any thoughts on what this pain could be coming from. Is it just "cancer pain" which is what one nurse said last night? I don't really understand that. Is it radiating from her liver? Could it be caused by Ixempra? I know no one really knows just hoping for something to get her through this, she's so tired and thin.

One more question, her onc is hesitant to use Avastin, I think because some of the recent reports out there, but so many women seem to have good luck with it and it seems more tolarable than Ixempra? Any thoughts?

Thank you all so much I will give her all your love! Jennifer
