Wondering as she left the house for a medical visit, to me, she doesn't seem very well?

She isn't. She has a major infection in the chest area, that would make anyone feel poorly.

They'll have to carry her out if needed.

She thinks she can win this...her health and her kids come second.

The doctor obviously told her it's fine to go back in the house, so I guess she's not that ill. Katie said herself she felt fine.

Didn't she say it was smelling? and it doesn't normally smell like this?

Aye, sounds like the wound is infected
