The ankle is a place where the body is subjected to a lot of force, and there are many nerves and ligaments gathered. If the ankle is broken to the point where there is edema, the fascia or ligaments may also be bruised. Depending on the degree of the fracture, if it is very serious, for example, if the gastrocnemius nerve is damaged, it is edema from the lateral ankle tube into the ankle, and it will compress the gastrocnemius nerve to appear gastrocnemius nerve pain. Once this happens, the lower limb should be elevated and iced during the acute phase, and it may take 1-2 days for the redness and swelling to subside, after which rehabilitation or physical therapy treatment should be started. It is recommended that the patient visit an orthopedic or trauma clinic. If symptoms of foot drop or nerve deficit appear even after the edema has subsided, the patient should go to neurology for adjuvant treatment at an early stage.
