Back at doctors and hospital today they did more x rays and have told me she has badly sprained her ankle and it could take 3--6 wks to heal
Hello!
Let her rest adequately and take sick leave from her school for a period of 1 week.
She should avoid weight bearing and also apply ice packs and continue taking ibuprofen to get better.
If symptoms continue then you should consider an MRI and follow up with an orthopedician.
Take care!
