Thanks for the query
It looks like you have suffered from a small ligamental tear in the ankle
Ligamental tears takes more 12-16 weeks to heal and some amount of dull pain will be present. Do not worry, give it some time to heal.
Take pain killers only when the pain is unbearable. Topical painkillers of aceclofenac
gives quick relief.
Further work up for differential diagnosis can be done with an orthopedician by getting an MRI
I hope I have answered your query
