With a metatarsal fracture, it is usually within 7-10 days that the swelling gradually reaches relief from its peak. That is, 7-10 days to reach the peak, the swelling will be gradually relieved, and finally reach complete relief, some may last up to 2 weeks, the longest will last up to 4 weeks. The most obvious period of swelling is 7-10 days, and then gradually relieved, part of the patient’s own recovery or physical condition is good, that is, 7-10 days can reach the tendency of obvious swelling subside. For patients with more obvious swelling and persistent swelling with no obvious relief, oral administration of Meiziling as well as localized microwave therapy and elevated braking of the affected limb can comprehensively promote the reduction of local swelling. For metatarsal fracture, if there is no obvious separation and displacement, cast immobilization and elevated braking of the affected limb can be carried out. The fracture should be reviewed every 6 weeks, and flexion and extension exercises and weight-bearing activities should be performed according to the healing of the fracture.
