Swelling occurs after a leg fall and can be dealt with in the following ways: First, if it is a mild injury and swelling, local braking and cold compresses can usually be applied, as well as oral anti-swelling and pain-relieving drugs, such as Cao Wu Jia Su tablets and Pan Long Qi tablets, which can quickly relieve the swelling and pain symptoms, and the patient will also recover completely in about a week. Secondly, if it is a serious injury and swelling, X-ray examination and MRI examination are needed to confirm whether there is fracture or dislocation. If it is a joint injury, the structures within the joint, such as meniscus, cartilage, and ligaments, should be determined to determine if any damage has occurred. If it is determined that there is serious damage as described above, treatment is required, even requiring surgical fixation, ligament reconstruction, meniscal suturing, etc. After several methods of treatment mentioned above, the leg swelling symptoms can be gradually relieved. Usually, patients should strengthen the leg muscle protection to avoid injury.
