Really bad ankle pain?? Please help!?

So the otherday I was doing cartwheels in my livingroom and I did one really hard into a wooden chair. When it first happened I could walk but like 10 mins later I could limp. I put ice on it for like 30 mins. Now like a week layer it is still really brides and swollen. If you like feel it, it is really bumpy I guess. It's kinda like on the inside of my left ankle. Could anything be wrong at this point? Should I see a doctor?
