Can't smell.....

Last night I was roasting chickens and realized I couldn't smell them cooking.  I tried to smell a jar of 'Vicks' and couldn't smell that either.  So now I am worried because I can't smell ANYTHING!!!  I'm not sure if it's because of the chemo drugs burning my sinus' or my sinus infection that seems to be lingering.  It's on my list now of things to ask my oncologist on Thursday.  I am hoping that it's all just temporary like the other side effects of treatment.
