Torn ligaments in my ankle, saw doctor said it was ok and sent me home?

Today i torn my ligaments in my ankle, now it all swollen, i went to a and e and saw a doctor, she gave me x rays told me that no bones were broken and sent me home with a leaflet and told me to put ice on it, but if a ligament was torn, aren't the suppose to bandage it or at least give me crutches for support? anyway just wondering cause walking for me is seriously hard for me. thanks =)
