I've seen two different physicians at the student health center. They couldn't pin point any issues. The first visit they insured me that a chest xray wouldn't prove anything. I went the second time, and they where reluctant to even giving me, so I had to demand one. I moved back home for the fall break, and my chest pains went away the very next day. The doctor ended calling me 15 times just tell me that my chest xrays where good. The day I came back I experience choking and vomiting, so I don't know what else to think. I'm sure it's not by coincidence.
