Patient: In June of 2014, I was playing this game where I had my hands out in front of me with my elbows bent. My left hand was hit forcefully and my arm went back and jolted my neck and shoulder. I originally felt pain in my left elbow and shoulder, and it was painful for me to hold my arm up. I had my arm in a sling for a few days, and then the pain was slightly less severe.About a month later, I attended an ochestra camp for a week where I played cello for about 8 hours a day. The pain came back and started to affect my neck as well. From then on, my neck always hurt. It is in the cervical spine area.I went to my family doctor who said I sprained my shoulder. The next couple of months, the pain got worse, usually at a 4 or 5 out of 10. I went back to the doctor and started physical therapy.They discovered a knot in my left shoulder and were able to massage it out after a couple of weeks, but my neck pain kept getting worse. The highest pain level I have felt since PT was an 8 out of 10.A few weeks ago i kept feeling sharp stabbing pains in my left side by my ribs. They only lasted about 30 seconds every time, but the pain was so bad that I couldn’t breathe or move. This stopped after about a week, but now I have pain in my left collar bone. The pain now goes from the center of my neck to my fingertips. If I move too suddenly, i feel a pop in my neck and a tingling sensation goes through my arm.I have also started feeling pain when I turn my neck, usually in the base of my skull on the left side and my left collar bone.I have stopped sleeping with a pillow under my head and stopped doing any strenuous upper body excersises per therapist’s instructions and I have now stopped PT because it was making things worse. What now? I am only 15 and have no clue what is wrong with me. Any help or advice is appreciated!
