question: I have upper abdomen pain and through the sternum. I cannot lie on my left side, but I can lie some what comfortably on my right. It is hard to breath sitting up right and if I raise my breasts I can breath a little easier but it hurts to do even that. The pain in the abdomen is bilateral. I did do some heavy pulling and lifting this weekend. I also have a temp of 100 degrees Fahrenheit.
