Hello and thanks for your question.
It's my first priority to help you.
I understand your concern.
As per your description,if she puts weight on her foot and walk without pain then you can call your GP.
Otherwise fracture,ligament tear,tendonitis should be ruled out at ER as she has history of osteoporosis and she is more prone to have even a hair line fracture.
Continue cool compresses.
Use crutches while walking.
Wear ace bandage for compression and immobilisation.
A referral to orthopedist is advised in case of fracture.
Feel free for further queries. It's good to discuss rather than quit.
