Suggest Treatment For Swelling And Bruising After Spraining Ankle

hello. i had a bad sprain a little over two weeks ago. the bruising is less now, and the swelling but it still hurts conderiably. it heard a pop for certain and the ankle seems very unstable. there is also a notable indentation under the outside ankle and on the side and top of my foot. there is also one on the outside of my calf which also hurts. my friend said i may have ruptured a tension or something? what should I do? i want to make sure this mends properly.
