Sharp, burning pain in the upper right side of my neck and my right hemisphere of my...

...brain? I am 15 years old, I believe I have had this pain since I was 10 or 11, perhaps earlier. I feel a sudden sharp, burning pain in the back of my neck. It spreads out quickly across my neck and the top of my head. Sometimes, my head begins feeling like "pins and needles". (You know that feeling you get when your foot falls asleep? It is caused by a decrease of blood to that certain part of your body.) This pain occurs mostly when I am moving around a lot like running, turning around quickly, boxing, ect. The pain starts in what seems to be a tendon or muscle on the back of my neck, on the right side. It is up by the base of the skull, cerebellum area I persume. The pain starts out as a sharp pain, as if I pulled a muscle, then spreads out, with a burning sensation, throughout the rear of my neck and the right hemisphere of my brain. Then it feels as if I lost blood flow to the right side of my brain. I often find myself to be very dizzy afterwards. This pain occurs maybe once or twice a month, more or less. It only occurs if I strain my neck by turning my head quickly. Anyone have any ideas to what this might be?
