Running and jumping can lead to the formation of small spikes of bone near the ankle joint. These bone spurs form in the capsule of the joint. They can cause a lot of pain. Any damage from a previous ankle injury can also show up in new ways. For example repeated motions during practice can cause some soft tissues to get pinched if ankle
ligaments were torn in the past.
There are many other possible causes of symptoms in the ankle. Talk to the coach and see what he or she thinks. Perhaps a change in the training schedule is all that's needed. If the symptoms persist, a visit with an orthopedic doctor may be helpful.
