How did crural sprain instep outside swell to do

If the outside of the foot is swollen after sprain, you should first go to the hospital for X-ray examination to determine whether there is a fracture. If there is a fracture, it is usually fixed with plaster. If there is no fracture, ice the affected area first, and then heat it 24 hours later to promote blood circulation. At night, you should raise the affected limb to speed up blood circulation.
