There is no fastest way to recover from a minor foot sprain. For sprains, there are five main principles of treatment, which are protection, rest, ice, compression and elevation, which can be more conducive to recovery. Within 72 hours of the injury, patients should apply ice for 15 minutes every two hours to reduce swelling, and hot compresses 72 hours after the injury to promote blood circulation and prevent blood pooling. Patients should pay attention to protect the injured area, take sufficient rest at home, and not overdo the activity. If conditions permit, the sprained part can be wrapped with elastic plastic film, which is conducive to stabilizing the damaged soft tissues. After a minor sprain, the above five principles of protection, rest, ice, compression and elevation should be followed. If there is serious swelling after a sprain, it is necessary to consult a doctor for other symptomatic and causative treatments.
