Hi. I'm online and happy to answer your question today.
It sounds like you are doing everything correct and she is going to be OK. But, as you said, she is ninety and folks that age break easily.
The area that I would be most concerned about would be her wrist. I'd continue with the tylenol and ice packs and, if it doesn't seem to be showing any improvement in a day or so I'd take her in to see her MD for possible xrays.
Does this make sense to you?
And, now, the obligatory word from our sponsors: :o)
