Suggest Remedy For Swelling And Soreness In The Leg Post Injury

I slipped on some ice, I did t fall and hit it. I regained my balance, but definitely hurt my self, I believe I sprained it. This happened about a week and half ago, my symptoms have gradually gotten worse. Swelling, tenderness to touch and bending it or sitting to long aggravates even more. Using ice and Motrin. Do you think this is just a bad sprain? Should I see my dr at this point?
