The time to recover from a ligament injury is determined by the severity of the patient’s injury. The recovery time varies depending on the degree of ligament injury. If the ligament is not ruptured and there are only minor symptoms such as pain and edema, generally speaking, 3-4 weeks can return to normal, during the recovery period, we should take non-steroidal anti-inflammatory drugs or blood circulation drugs according to medical advice, while using a cast or brace to fix; if the ligament is torn or ruptured, the joint will be unstable and even dislocated, requiring ligament repair surgery, which generally requires 6-8 weeks of recovery time. When ligament injuries occur, it is important to take strict bed rest and not to do any weight-bearing exercises too early. Eat a diet rich in protein, such as chicken and fish, and do not eat spicy and irritating foods.
