Pain in my upper arm and shoulder when i move it? - upper arm pain more condition_symptoms

I had a football game yesterday evening and I collided and a third player and slid on the floor in the left shoulder and arm. Last night I woke up in pain, and today it really hurts to lift and to make certain movements. It does not hurt to touch, do not hit muscle or anything, and has also been increased. What could be the problem?
