My mom has had pneumonia for over a week now. Her body has become resistant to any prescription drug, so her oncologist decided today to put her in the hospital for a few days to give her a drug intravenously, and also give her oxygen. He also suggested giving her oxygen to take home after she gets out of the hospital. I am just wondering if there is anyone that has been through this before, and eventually no longer needed the oxygen. I just fear that she will not be able to be treated, and will have to stay on oxygen and won't ever return to normalcy. My mom is stage 4, nsclc at age 54.
