tykerb sore mouth and tongue

[grandma2]

this is just my first week on tykerb and the fatigue is very strong. yesterday i noticed my mouth felt sore like a bad burn from something hot. when i looked last night it looked like a bunch of sores on my tongue. mouth, throat and eyes extremely dry. does anyone have suggestions how to handle the sore mouth and tongue? also i've noticed so many of you are taking herceptin, tykerb and xeloda with all kinds of variations. are you all in usa? i ask this because my onc is so emphatic about doing what is protocol with no deviations. i'm not sure if it's just her or what. going tomorrow and not sure how to handle it cause she still says se's of last week were not from xeloda. today i got a form from roche pharm. re my se's and they want docs info. but if she insists xeloda wasn't the cause then ? please forgive me if i've asked these questions before. i've been having bad chemo brain with these new drugs. thanks, gm
