You should never use hot water to soak your feet after a broken foot, because the blood vessels will break after a broken foot, and then hot water soaking will cause further expansion of the blood vessels, resulting in more bleeding from the broken blood vessels, making the swelling of the broken foot more obvious, which is not conducive to recovery. The correct approach should be to apply a cold compress immediately after the broken foot, cold compress for 15-20 minutes, and elevate the foot to help reduce edema and avoid excessive swelling. Hot water foot soak is usually applied 48 hours after the broken foot, the damaged blood vessels appear to heal and no longer bleed, and the hot compress can increase the blood circulation around the area, so that the parts with bruising and inflammatory edema can accelerate blood circulation and promote the elimination of swelling and edema.
