I have had pain in the upper stomach, in the area below the sternum.  It feels like I have been punched in the stomach.  It doesnt make a difference if I eat or not, or have a bowel movement.  I dont have a fever, but do feel warm.  Pain gets a little better when I sit, buy lying down or standing up it is about the same.
