Since yesterday night I have been having chest pain when I was sleeping and every time I turned I could feel it. I can feel it more on the left side in the front from my chest bone down my below my left breast  to my back bone. I have been sitting a lot on the computer studying for exams.  I can also feel pain in my neck right down my left shoulder and arm. I was wondering if this is a muscle pull or is this something to be concerned about that I have to see my Doctor.

Please advise.

Thank you!
