Ankle ligament tear is divided into acute phase and chronic phase, and the specific symptoms of different periods are as follows: 1. Acute phase: redness, swelling and severe pain appear, the outer ankle will bulge with a bag, and the inner ankle will also bulge after pulling, so you need to consider whether the ligament tear in the ankle is a deltoid or medial collateral ligament tear; 2. Chronic phase: the affected ankle is thicker than the healthy one after tearing, but the pain is not as severe as the acute phase, it is chronic pain. The ankle can’t be supported for a long time, even the ankle joint shakes, and the foot will be broken if you are not careful when walking on flat ground, the reason is not the lack of consciousness, it is because the characteristic of the ligament is that the ligament will not grow again after tearing and rupture, but only continue to recover according to the original position, so the tension force of the ligament as well as the role of the fixed ankle decreases. Depending on each person’s situation, if there is a certain impact on function, an MRI is required at the hospital and surgical intervention should be performed if needed.
