Sprained ankles are one of the most common injuries for kids and adults alike! They are annoying because they are persistent. This stems from the fact that they are often quite easy for people to ignore and push to the side. This creates an unstable and weak ankle. This weak ankle is continually rolled sprained to the point that it is almost beyond repair. This is extremely popular in netball and football players. When you combine this unstable ankle with the stop start and quick direction changes of modern sports, you open your body up to the risk of injury further up the body (low back, hips etc.).
You can help prevent this with simple exercises. They are to be done in stages and never to be painful. Feeling the ankle work and to be fatigued is fine, but pushing through pain spells disaster. No pain, no gain is potentially the worst saying in the English language! You are continuing to damage the ankle and no amount of rigid sports tape will keep it from failing. The only way to avoid the knife is to have the ankle treated and then rehabbed with specific, patient exercise rehabilitation.
