Hi Imerson..you probably should get an X-ray for any bone issues or MRI is good for any tissue damage. If you don't have bag of ice use a frozen bag of peas or corn and ice for 15 mins and off 15 mins. Wrap the knee with ace bandage or black knee support until u can get to the doc. does your knee crack? Take ibuprofen as directed for swelling. Hope you can get to the ER or doc soon.
Take care
