When swelling occurs in the area of the ankle, the first step is to actively identify the cause. If the swelling is caused by a sprain, any movement performed needs to be stopped immediately after the sprain. You can use elastic plastic wrap to wrap the swollen and sprained area to effectively reduce bleeding and swelling. Intermittent cold compresses within 2 days of the sprain can occlude the bleeding capillaries, reduce bleeding, and reduce swelling. After 2 days of injury, local hot compresses can be applied to promote local blood circulation and relieve swelling. The affected limb should be elevated to avoid sagging, not to be pushed or massaged, and can be treated with mannitol injection and sodium hesperidin for injection to reduce swelling by dehydration. 2 days later, blood-activating drugs can be applied to relieve swelling. At the same time, an MRI should be performed to determine the extent of the injury. If there is an indication for surgery, active surgical treatment should be performed. If prolonged standing causes swelling, you also need to correct the body posture, actively elevate the affected limb, and apply appropriate hot compresses and scalding. You can apply the drug Mizarin tablets to promote local blood circulation.
