Patient: Hi. I have had a very emotionally stressful few days with little sleep, loss of junk food, and too much caffeine at odd hours. I just laid down and noticed a sharp, radiating pain in the upper left side of my back and into my chest, moving slowly throughout my upper back and then into my abdomen. It is not muscular, and very noticeable, though not to the point where I want to scream or cry. It is somewhat worse laying on my side.
