Upper Back Pain

Patient: Hi. I have been having upper back and shoulder pain on the right side for over 4 months now. Feels like dull aching pain and some spots tender to the touch. Pain is constant, even at rest. Have had CT scan of the chest (no contrast) and open MRIs of the thoracic and cervical spine (no contrast). Prior to the CT scan of the chest I had a chest X-RAY which showed what the doctor now thinks were blood vessels in the lungs. Is there a chance that both the MRI and CT scans missed something in my lungs?
