Playing Hockey, I Was Tripped Up Along The Boards As

Playing hockey, i was tripped up along the boards as i was falling my hip pads shifted and my hip/left buttock mad direct contact with the ice. I was able to get up and move gingerly for about 20-40mins pain subsided when adrenaline kicked in. But everytime i sat on the bench it was extremely sore and tender.
Today (The day after) i was able to play again with little pain but still everytime on the bench it hurt. I couldnt do a stretch: sitting indian style and leaning towards my left knee because it hurt so bad and then i tried putting my ankle on my right knee bent and i could only relax it about 30% before it seemed like i was hyper-extending my muscle in my hip/butt.

I dont want to go see a physician, but i figure id ask if it needs attention.
