In the case of a hamstring injury to the knee, immobilization of the knee should be performed immediately after the injury. Depending on the location of the injury, if the injury is relatively minor, the knee can be immobilized with a sports knee brace. If the injury is severe, most people need to straighten the knee and immobilize it with a knee brace or cast. The immobilization period is usually more than three weeks to give the injury enough time to recover. Cold compresses should be applied immediately after the injury, using ice packs or blood-activating cooling sprays, to reduce localized exudation, bleeding, and swelling, thus speeding up the healing of the injury. Oral administration of Shujinzhuyu Tang, Horse Chestnut Seed Extract, and Ibuprofen Extended-Release Capsules can effectively relieve pain and promote recovery from the injury, and combined with acupuncture treatment can lead to rapid elimination of the symptoms.
