My 8yo has badly sprained her ankle a few times over the past 5 years and every month or so, often after a long walk but not always, will complain that her ankle is sore and it hurts to walk on it. Often it's not until the next day. It's not so bad that she can't bear weight on it, but it is clearly uncomfortable. Her shoes always wear out on the outside of the sole, so the ankle must be under stress the whole time.
Other than the usual rest/ice/compress etc what can I do to help strengthen it? I'm assuming the GP would be no help and that it needs a physio? Or does she need orthotics? It's starting to limit her exercise and I'm concerned it will only get worse as she gets older.
