I am having severe back pain in my upper back, sometimes radiating through into my chest. This pain started about three weeks ago, and has gotten steadily worse. Muscle relaxers do not seem to be of much benefit. Even pain medication does not relieve the pain. The only time I am at ease is while lying down. Whenever I try to turn over or move after resting, the pain reappears. Turning my head and breathing deeply is painful. The pain is not directly over my spine, but to the side. I do not remember injuring myself, but I am active, and I suppose I could have suffered an injury without realizing it. There is no pain radiating into either arm. The pain shows itself in different ways. Sometimes it manifests as a burning pain, sometimes as as a sharp stabbing pain. At first, it was across one area of my back, but now it seems to be spreading. I am not a wimp, and I can probably outlast whatever this is if I know it will go away, but if it won's, I will do what I have to do.
