Suggest A Remedy For Sprain In The Ankle

I sprained my ankle severely playing basketball, my foot rolled in, the sprain is on the outside. The xray came back negative. Deep purple coloring occurred both on the inside and outside of the ankle and around my toes. It has now been two weeks and the swelling and coloring are mostly gone. However I am still experiencing pain around where the tibula "bump" is. Walking is still somewhat painful. Also, there is discoloration/bruising up my calf. I am debating whether or not I need to see a doctor. Could there be damage that needs treatment, or will this heal in time?
