Ankle sprains are very common and some doctors don’t pay much attention to them. Some doctors don’t pay much attention to it and send the patient home with a little Fotarine and a spray of medicine. If ankle sprains are not treated properly, they can leave behind long-term instability and swelling of the ankle joint, which is very common in outpatient clinics. About 20% to 30% of patients end up with long-term ankle pain and swelling, even leading to severe osteoarthritis, and some of these patients are the result of improper early treatment. A sprained ankle can be treated on its own if there is no fracture. There is a simple way to determine if a fracture has occurred: press the outer ankle of the foot with your hand, the place that protrudes from the outside of the foot is called the outer ankle. If there is no pain and the pain occurs in the area in front of the outer ankle, this is often a ligament injury. Introduce several methods of self-treatment after ankle sprain: (1) Do not continue to walk after the sprain, but if the sprain is mild and the swelling is not strong, you can walk. (2) Ice: Some people have a wrong concept, once sprained, take the massage or hot compress method, which is wrong. Because the sprain is overstretched ligaments local blood vessels have ruptured, and then massage will make more and more bleeding, swelling also increased. If the hot water compress will make the blood circulation faster, will also increase the swelling and pain. The method of ice can make the blood vessel contraction, reduce swelling and pain, generally ice can last for three days. Later, the treatment will be changed to hot compresses and physical therapy. (3) pressure bandage: serious sprains should be fixed, available bandage fixed, more serious with a cast fixed, because not fixed in the future will leave chronic pain and unstable feeling. (4) elevate the affected limb: sleep on a pillow under the foot, elevate the affected limb to help reduce swelling. If the sprain is serious or there is a fracture, you should go to the hospital to see a foot and ankle doctor for professional examination and treatment.
