Whether or not a torn ligament will heal on its own depends on the degree of the ligament tear. If the ligament tear is mild, or if the ligament persists well, it can heal on its own; if the ligament tear is severe, it will not heal on its own. If the ligament tear is mild, the torn area should be fixed by plaster or brace, and at the same time, topical ointment for blood circulation and blood stasis should be used, and oral anti-inflammatory and analgesic drugs should be taken under the guidance of doctor for treatment, and local acupuncture, massage and physiotherapy can also be performed, and generally speaking, the torn area will slowly heal by itself; if the ligament tear is serious or even broken, it is impossible to heal by itself, and surgical repair such as stitching or ligament reconstruction is needed. During the ligament recovery period, you should pay attention to rest, do not work too hard, do not eat stimulating cold food and avoid drinking alcohol to prevent aggravation of the condition.
