Stephanie,
I am so sorry to hear your Mother is having side effects. I hope that the doctors act quickly to find the cause of these symptoms. I would think stopping all treatment would be in order. It seems some baseline tests should be ordered immediately to rule out any other problems. I think I would request a muga scan as one test.

I once suffered an obvious severe allergic reaction to a chemotherapy drug that was being infused for the first time. In that case we knew it was 100% caused by a chemotherapy. I think until they do some background tests it's hard to say if it is Tykerb or not. There is data out there on Tykerb and Xeloda. I am sure the doctors can consult with the drug company or other oncologists experienced in this drug line.

I wish you and your Mother the best.

Hugs
