Most people have suffered a bad ankle sprain from an inversion injury, but some go on to have such significant laxity that they can't trust their ankle. This population usually benefits from taping or bracing. You would also suffer from ongoing lateral calf muscle tightness (peroneus longus and brevis cross the lateral ankle and kick in when the ligament is not doing its job). If this sounds familiar, consider getting assessed for ultrasound-guided prolotherapy to the distal tib-fib interosseous ligament, anterior talofibular ligament, calcaneal fibular ligament, bifurcate ligament, and possibly more. The aforementioned ligaments are usually the culprits when ligamentous laxity is suspected after an inversion injury.
