It usually takes 1~4 weeks for the swelling to go down on the outer bulge of a broken foot, but if synovitis, ligament damage, etc. are present it will take 1~2 months or even longer. If it is a more mild broken foot, while swelling 1~3 cm, the degree is relatively mild, then it generally takes 1~2 weeks to begin to reduce the swelling, while the pain in the ankle area gradually reduced, the complete reduction of swelling may take 3~4 weeks. However, if the swelling is accompanied by synovitis, ligament damage, etc., the recovery time is relatively longer, and it is necessary to consult a doctor in time to carry out X-ray or MRI to rule out the case of bone fracture. Under the premise of combining scientific treatment, it usually takes 1~2 months, and may take longer if the condition is complicated. There is no fixed period, subject to the doctor’s recommendation.
