The symptoms of fibular ligament damage include, first, pain, especially noticeable tenderness or pain around the fibula when bearing weight, which can further affect weight-bearing walking. Second, swelling can occur, particularly after prolonged weight-bearing walking, leading to localized swelling that gradually subsides with rest. Third, joint instability can also occur as the stability of the entire joint deteriorates after ligament damage, resulting in instability during prolonged weight-bearing activities, and in severe cases, affecting joint mobility and damaging the joint cartilage.
