Hi. I have been having pain in the left side of my back - below shoulder blade and radiating into the rib area below the shoulder blade. It only hurts when I have been laying down with pressure on my back but I have been getting sharp stabbing pains, mostly early morning hours before I get up. The pain has started to wake me up. I can move a bit and it subsides but eventually comes back in a few minutes. It does not seem like it is in the ribs but the area between the ribs and muscle. Taking a deep breath brings on sharp pains but again, only while laying on my back. I am a back sleeper because I have some tendon pain with my shoulders if I sleep on either side. There is no pain if I lean against a wall or chair and there is no swelling or pain with movement. I have full range of movement of my arms, can stretch and easily lift up to 50 pounds. I had this pain a few years ago but it was temporary and not as severe. This time it started about a week ago. Can not associate it with any known over exertion and I have not had a cold or any coughing. I did talk to a doctor about it several years ago and routine exam showed nothing wrong. I am female, 51 years old general good health with normal activity level.
