Baseball injury

Patient: Hi, I am a 18 year old male. My injury happened very oddly. I was playing baseball and as I swung the bat, it felt as if a shock traveled from the bat through my arm to a point somewhere inbetween my shoulder and neck. I cannot throw a baseball or football without severe pain. I have pain even when I do nothing. I saw a doctor and the X-ray was clean in my shoulder. I did therapy and did not work. I did not think to ask about checking my neck. Is there a possibility that shoulder pain can come from something in the neck? Thanks
