What do you think is wrong with my wrist?

So... around a year ago, I took a spill on some ice and landed on my right arm, fully extended, and hurt my arm. At the time it was all in my elbow; I couldn't move for a few minutes and I think it maybe got sprained, but I'm not sure. There was no swelling as far as I can recall (I didn't think to check for it though). I never went to the hospital for it though. So it stopped hurting about 2-3 months after I fell. Then I had a pain in my wrist every time I moved it forward or backwards too far. As the year progressed, it got steadily worse with out me consciously knowing until a few weeks ago. I can barely move it forwards and backwards at all now, and I tried doing a handstand and nearly started crying. I don't know what's wrong with it, or if I should have it checked out. Sometimes, my bad wrist feels colder than my good one, and my elbow hurts every so often now, but not that bad. What do you think it is, and what should I do?
