How long it takes for a contusion to heal itself depends on the severity of the patient’s condition, the site of the contusion, and the individual’s constitution, which should be analyzed on a case-by-case basis and not generalized. In the case of soft tissue contusions with mild symptoms, spontaneous healing usually takes about one month. However, patients need to take care to prevent infection and reduce activity. In the case of bone contusions, spontaneous healing is usually not possible and symptomatic treatment is required. Recovery time is shorter for minor bone contusions, and longer for bone contusions combined with cartilage contusions or even ligament tears. In addition, recovery time is longer for bone contusions of the lower extremities or near the joints. In general, bone contusions require at least 3 months of recuperation, depending on the individual. Patients with contusions are advised to go to the orthopedic department of a regular hospital in a timely manner to have the cause of the injury examined by a professional doctor for symptomatic treatment. Avoid strenuous exercise in daily life, try to elevate the affected limb when resting, and take local hot compresses, baking electricity, and closure to relieve symptoms.
