Hi, I am a medical doctor from Europe. I also have symptoms that you have. I had stress fractures in my costovertebral joints and a rib subluxation. Whenever did your symptoms started, any injury before that? Mine was a ballet injury. On witch segment do you have pain? My is thoracolumbar junction. Sometimes radiologist only look for herniated disc, they don’t even look the joints. This small joints are responsible for 40% of chronic back pain – in T spine there are costovertebral, costotransversal and facet joints, and they have this nerve endings that can really Hurt, due to arthritic changes or injury. You should do MRI with axial slices not only sagittal, best sequnces are T2 and STIR to see i there are any arthritic changes or inflamation. I am a resident of sports medicine and rheumatology.
