of ankle takes nearly 3 weeks to settle down.
In a way it is worse than a fracture
as you never give proper rest to your foot.
Do hot saline fomentation twice a day.
Take some anti inflammatory like ibuprofen
400 mg three times a day for 5 to 7 days.
Apply crepe bandage on the ankle in day time.
Wait for another 2 weeks.You shall be alright.
