How long does it take for ligaments to pull and cast?

After ligament strain occurs, if the strain is not very serious, you can choose conservative treatment, use plaster for a period of time, this time is basically 2 to 3 weeks. During this period, you need to cooperate with anti-inflammatory and analgesic drugs, blood circulation and stasis drugs as auxiliary treatment. After three weeks of fixation, the patient can go to the hospital in time to do relevant examinations to see the recovery situation. If the recovery is good, the external fixation can be removed, and proper joint and muscle function exercise can promote the recovery. If the ligament strain occurs in a particularly serious patient, such as a complete rupture, the patient may need to take surgical treatment to treat it, which can promote the recovery well.
