Ask the chemo or radiation center for more hydration infusions, Anxiety meds, up the pain meds if needed, and possibly corticosteroid like decadron, prednisone to reduce inflammation, and promotes better being, increases the appetite, consume additional protein, calories for healing, keep rinsing, and ask about an aspiration machine..suction pump for home use, HBO treatments to assist healing, and wound management, which is sometimes combined with HBO. Good luck with the final week.
