I play hockey at a high level and during a game early this week I was hit in the face. At first nothing seemed to be wrong but after the game I cracked my jaw and it has killed ever since. I can open my mouth about half-way without pain but to open it all the way really really hurts and the muscles on the right side of my jaw feel very very tight. Also, if i force my ja open all the way and i wiggle my jaw there is excruciating pain and I can also hear a 'creaking' sound on the right side. Is my jaw dislocated? Its been 3 days now and it hasn't gotten better at all

Thanks,
Claudio
