Shoulder Injury

Hi,
Saturday I had a Rugby game and I tackled this guy. He turned to take the hit on his side, and my right shoulder hit his hip bone, and immediately i knew something was wrong. I told coach I had to come out because I had very little use of my right arm, it felt really floppy and as if I could not control it. I put ice on it (The outside of my arm, pretty much right where it connects to my shoulder), but could not feel the coldness of the ice. A nurse at the game looked at it, said I might of pinched a nerve, and she checked for a broken collar bone but she said it looked fine.

About 30 minutes later my arm, from the elbow to my shoulder, I couldn't really use. I can point my arm towards the sky (with some difficulty), as if I was pointing straight above, but if I bend my elbow so my  hand is touching my chest (kind of like doing the pledge of allegiance) I cannot lift my elbow up to make it higher then my shoulder blade. I have small specks of bruising on my shoulder as well.


This is really bothering me and I would like to know if I should visit a doctor for it, or if I should just ice it and give it a few more days. Much thanks.
