Rib or muscle under shoulder blade

Our user asked: "My primary doc referred me to an osteopath. I preferred to go to the Physical Therapist. Never the less I went to the osteopath. the reason: I have pain when I lay down on the bed for sleeping or resting. I am fine when upright, walking, sitting, bending etc. When I lay down there is a pain under my left should blade and it goes to the front part of my chest. I have been sleeping sitting up. The osteopath experience really was upsetting to me. He didn't explain a thing to me. He asked me one question which was what does the doctor think the pain is and where is it? My primay doc said he thinks that it is about my 7th rib out. The osteopath thinks that I am thin and my ribs have a tendency to look like they are out because I am thin. 5"5 130 lbs. He twisted my in these horrible contortions and popped my bones. I have not experienced any progress with this method although it has been only 5 days. I do not want to go back . I have had great results with physical therapy in the past and I do not know what to do. Go back to the osteopath when the doc and the osteo did not commit to whether is was my rib or muscles. It seems wierd to me that the pain is not a problem until I lay down and that I can't lay down and sleep sitting up. I feel a slight nausea in the morning from the pain when I slide down when I am a sleep. There is some tingling to my elbow. Could you help me know what this might be and would'nt I benefit more from physical therapy rather than an osteopath? Thanks"
