Hello,
Thank you for your query at DoctorSpring.com
It looks from your details that most probably you had injury to your tibiotalar ligament.If there is pain and associated weakness at present then you should have a MRI scan of this ankle.Most probably you may had grade 2 or 3 tear which may need surgical intervention.
Till then you should have a protective ace bandage over affected ankle.
Hope this will help you.
Feel free to discuss further,
With best wishes.
