If you injure your knee by running, you should first rest and apply brakes to your knee to prevent further damage to your knee and to provide early pain relief, and go to the hospital for early examination, including X-rays, CT and MRI to rule out bone and ligament damage. If there is an injury, early specialist treatment and, if necessary, surgery are required. If there is no fracture or ligament injury, the following treatment can be performed: First, early cold compresses can be applied with frozen mineral water or ice wrapped in a towel, which can play an early role in relieving pain, hemostasis and swelling, while early spraying with Yunnan Baiyao can also play a role in relieving pain and hemostasis; second, early oral medication should be administered. Secondly, early oral medication, such as meloxicam and celecoxib, can be used to treat the pain, and in the later stages, oral medication can be used to activate blood circulation and resolve blood stasis, such as Dazhiri capsule and Panlong seven tablets.
