To add to that - if she can't walk and hasn't been able to since she hurt herself there could be a broken bone. Did she have an xray?? It is not usual for a 2yo to sprain / strain an ankle.

As for the panadol / nurofen - follow the instructions on the bottle closely. Painstop is a stronger medication - available from the chemist but I am not sure if they give it to 2yo (we do in hospital) but it also contains some paracetamol (panadol) so be careful with the dosing.

For tonight - ice pack over a tea towel and foot up in the air to try to stop the swelling and help with the pain. Good luck.
