My 94 Yo Gmother Has Been Weak, But Improving Even

My 94 yo gmother has been weak, but improving even doing crossword puzzles daily. Earlier her legs went limp, I caught her in my arms and mom & I got her on her bed. I asked her does it hurt, because of her facial expression, she nodded yes.
Once on the bed almost instantly she felt better, not realizing she had just said she was hurting.
She's anti doctor, dnr, etc... so mom & I are here offering what we can without forcing anything.
She still cracks jokes and is pleasant.
A blessing we appreciate.
