I would like to suggest you to elevate your leg and then apply crepe bandage in ascending order from your toes to your calf (not too tight). This will reduce your swelling. And your can also apply cold pack or ice pack on your ankle and feet for about 15-20mins for quicker results.
Next Steps
You can opt for ankle toe movements vigorously to help reduce your swelling to occur.
Health Tips
Avoid standing in one place for more then 20-30mins.
