I have been have back pain on the left side of my back underneath my shoulder blade. It hurts alittle when I breathe but it really hurts after I have been lying down all night. When I wake up in the morning it hurts so much...especially when I breathe and after awhile the pain almost goes away. I''ve had a back x-ray which showed nothing. I have been sick with cold like symptoms for about a week. What could be causing the pain when I breathe after I wake up in the morning. I am not a smoker.
