Did the oncologist do a "culture" of the area of concern in your mouth? That is how they can tell if it is fungal or not. Also some doctors know just by examining an area.
The acupuncture needles are not really supposed to hurt too much. I guess it depends if the acupuncturist decides to turn the needles to treat a deeper problem in a specific area. The only time my naturopath/acupuncturist hurts me is if he hits a nerve or a muscle. He apologizes and adjusts the needle. This doesn't happen too often, thank goodness. Acupuncture needles don't go down as deep as injection needles go. Your body might be a little more sensitive, because you are going through so much right now. Hopefully there might be less pain as time passes.
Take care.
