Every now and then I get a stabbing pain in the right side of my neck, in what feels like a blood vessel, every time I inhale. The pain is most intense at my neck but if I take a deep breath I feel the pain trail along the right side of my neck up towards the base of my skull. It usually goes away after I a while, but comes back at random times during the day. I am only 17 in college, I don't play any sports however I used to run cross country and play Lacrosse in high school. My diet isn't the best since I'm in college, but I'm not overweight, I'm actually in pretty good shape, I just don't understand what is causing this pain.
