@manykitties2 - That is too bad that your grandmother passed away from something unrelated after battling severe pneumonia for so long. I know how tough severe pneumonia can be as my mother currently has it.
Our doctor told us that because my mother is younger, she should have a good chance of a full-recovery. You know how doctors are, they never like to speak with complete confidence, it's always percentages.
I guess we'll just have to keep up with my mom's medications and making sure she is comfortable while she is recovering. She's been lucky enough to stay at home too, thanks to a great local home health care provider.
