My Mom, had walking Pneumonia once.
Her Doctor wanted her to be kept in the Hospital.
She, had other ideas. Went home.
Oh I'll be fine, she said.
It can be very dangerous.
Walking Pneumonia is named as such, not because you should be out and about walking around. But because, people have it and don't know it. Thus, they just go about their usual. Even if they are sick.
But then they may, end up in the Hospital.
My Mom, has a lung scar now.
Won't go away.
Her lungs are now, intrinsically weaker.
And as such, she has to be careful of any cold or lung illness, she has.
Which is more important?
Pleasing people and going out with them, and they know you are sick.
Or staying home and taking care of yourself? Mind you, your family can get it again.
There is bacterial Pneumonia or viral.
It can be, contagious.
Unless you have been on antibiotics for at least 24 hours.
I have had Pneumonia too.
Plus I have Asthma.
Your friend can still go shopping sans you.
She took the day off already.
Would she want you to go, if she knew you are sick and/or may have Pneumonia?
Whatever you decide, I would not tell your friend, at the last... minute.
And by the way, it took my Mom... a LONG time, to recover from her illness. A LONG time.
And you have kids in the home.
Kids and elderly, are more delicate if they get it. Meaning, dangerous.
