Wrist pain when turning left or right?

I was doing mitt punching for a couple of weeks, then I got a heavy bag to hit. I did that for 2 days, and on the second day I threw a hook to the body and my wrist felt almost broken. I could still punch, but twisting motions were out. So I gave it 3 weeks of no use, no punching anything, and it did no good. Currently it still hurts when I try to lift certain objects, and twisting to the right or left hurts. Basically I can still throw hooks and uppers, but straight punches cannot be done. Does anyone have an idea of what I have done to my wrists or how I could fix them?
