hello,,it sounds like structural damage,,,have you twisted it or ,,torn something,,,what where you doing when pain started,,,,if the injury is more than 72 hours old now ,,you can apply heat,,,20 mins on (always apply
heat or ice,wrapped in something as not to burn the skin),,,,,,,,underwings point is that any misalignment affects other structures,,,ankle will affect knee which will affect hip which will affect lower back,,etc,,,good luck
