Mom won't call oncologist. She has been treated for several months now with no issues with intravenous Opdivo for her lung cancer. She developed a rash and went to urgent care only and is throwing up the antibiotics. I want to cry and tell her to go to her oncologist. I think she's embarrassed. Rash is all over her bottom and has a brown discharge. She can't keep food down and rash started with 102 degree fever.
