How long it takes to heal a sprained ankle is mostly related to the severity of the sprain and cannot be generalized. There are two types of ankle sprains depending on the degree of sprain, including soft tissue injuries and fractures. If the patient is only soft tissue injury, most of them can recover on their own and heal completely within 2-12 weeks after the injury, and generally have fewer sequelae. If a patient has a fracture after a sprain, he or she needs to go to the orthopedic department of the hospital in time, and after treatment such as plaster immobilization or surgical treatment, he or she can usually recover in 3 months. However, if the patient’s physical condition is poor, or even combined with serious consumptive diseases, such as malignant tumors, etc., the time for full recovery may be further prolonged. Therefore, after the ankle sprain must first determine whether it is a simple soft tissue injury or fracture, if it is a soft tissue injury, can be protected by ankle guards, herbal soaks, poultices, etc. to promote the recovery, while if there is a fracture, you need to seek medical attention in a timely manner.
