One month ago my friend had the upper lobe of her lung removed due to lung cancer . Surgery was successful and No radiation nor chemotherapy necessary, indicated by all doctors involved. She has over the years I know her been an anxious and stressed type person. This past week, the fourth after her lung operation, she is having a heightened sense of smell and nausea . She is 64 years old and was supposed to get a pacemaker put in but that was postponed due to the need for the lung surgery. Any answers re: the heightened sense of smell including nausea and lack of desire to eat because of these symptons are appreciated.
