I don't know why I worry about it so much when it's not even me who's having the problem.
But today I asked her again how she felt, and she said that the back pain is gone, and the achy feeling is gone, but she said that she was really tired. I asked her how she slept and she said that she didn't sleep really well last night. She has had sleep problems for 20+ years now, so that wasn't surprising. But, I asked her if it felt like a normal tired or exhausted tired and she said exhausted.
She also told me that she had a little bit of stomach problems this morning. I keep pushing her to go to the doctors and she says "they'll say that nothing is wrong and send me home." I'm really sorry for my constant posting about my mom, and I really do thank everyone for their input.
