A medial ankle sprain is typically caused by an abrupt twisting, turning, or rolling inwards of the ankle. A medial ankle sprain can develop as a result of a fall or awkwardly walking onto an uneven surface. It can also occur as a result of deltoid ligament wear and strain. Symptoms include pain, swelling, and instability of the foot. The patient may have difficulty getting their foot to stay in place while standing. X-rays may be taken to look for any fractures but this is not usually necessary unless there is severe trauma such as a car accident. Most patients will recover from a medial ankle sprain within six weeks. However, if the injury is left untreated it may lead to chronic pain and arthritis. Physicians recommend resting the injured area and applying ice for 20 minutes several times a day for the first week after an injury. In addition, patients should avoid putting any weight on the injured ankle until further advised by their physician. Patients should also seek medical attention if they continue to experience symptoms beyond four weeks.
