In the event of ankle ligament sprain or tear, the patient will feel distension, stagnation pain or cut-like pain in the ankle area, while the ankle area is obviously swollen with extensive subcutaneous bruising, positive local pressure pain on palpation and negative heel percussion pain. If most of the ankle ligaments are ruptured, there will also be localized joint loosening and instability, and there will be obvious localized indentation when touching the area, and some patients will have numbness with decreased sensation at the end of the toes. Patients can get a clear diagnosis through ultrasound examination or MRI film. Treatment should be done by fixing the ankle area with braces, and also applying blood circulation and pain relief cream, golden ointment or taking oral fall injury medicine.
