How is an ankle sprain diagnosed?
Your doctor will ask you how the injury occurred and if you have hurt your ankle before. He or she will check your foot and ankle, your lower leg, and even your knee to see if you are hurt anywhere else. If the sprain is mild, your doctor may not order X-rays. But with more severe sprains, you may need X-rays to rule out a broken bone in the ankle or the foot. It is possible to break a bone in your foot or ankle at the same time as a sprain. In most cases, doctors order X-rays in children with symptoms of an ankle sprain. This is because it is important to find and treat any damage to the growth plates in bones that support the ankle.
