If the patient still has pain when walking 5 months after the right lateral ankle fracture, it may be due to insufficient functional exercises, poor fracture healing, or traumatic arthritis, etc. In this case, the patient should not do anything on his own. At this time, the patient should not take care of it by himself, but should go back to the orthopedic department for follow-up, to find out the cause of the disease, and then take measures such as functional exercise, application of anti-inflammatory drugs, surgical treatment, and so on. 1. Functional exercise: For some patients with ankle joint adhesion caused by insufficient functional exercise and subsequent pain symptoms, functional exercise should be strengthened first. For example, the patient can go to the professional rehabilitation department and ask the rehabilitation doctor to carry out passive activities on the ankle joint, so as to gradually loosen the structure of adhesion and expand the mobility of the ankle joint. 2. Application of anti-inflammatory and analgesic drugs: for patients with traumatic arthritis, it is necessary to reduce the use of the onset of joints and apply some anti-inflammatory and analgesic drugs to the patients, such as celecoxib, meloxicam and so on. For some patients who feel unbearable pain during functional exercise, such drugs can also be given to ease the pain. 3. Surgery: For patients with particularly severe adhesions, the ankle joint can be loosened for surgical treatment. For patients with non-union of fracture, secondary surgery can be performed to implant bone and internal fixation. It is recommended that patients consult the doctor in time, follow the doctor’s instructions, do not blindly use drugs.
