Hello,
Thank you for your query at DoctorSpring.com
I understand your concern.
I have a few questions before I can give my opinion:
1) For how many days has she been having the pain?
2) Is there any recent history of injury to the ankle?
3) What is her height and weight?
4) Has an x-ray been taken? If not, I advise you get an x-ray of the left ankle and foot, which will give further clue to the diagnosis?
5) What are the aggravating and relieving factors of the pain?
Awaiting your reply,
Regards.
