Whether a tendon injury can heal on its own is usually determined by the extent of the tendon injury. Because tendons are limited by their anatomical structure and have a poor blood supply, self-healing is difficult once the injury occurs, but it does not mean that it cannot heal on its own. If the tendon injury site joint mobility is good, not affected, the local swelling is light, and there is no obvious bruising, indicating that the tendon injury is relatively mild, rest for a period of time, the injury can recover on its own; if the tendon injury site joint mobility is affected, and the local swelling is serious, there is obvious bruising, indicating that the degree of injury is more serious, patients need to immediately go to the orthopedic department of the hospital for treatment, can follow medical advice If the tendon is completely ruptured, immediate surgery is required to anastomose the tendon injury. After the tendon injury, patients should pay attention to rest and get enough sleep, and at the same time, they can eat more high-protein foods, such as milk and lean meat, to facilitate the repair of the tendon.
