Hi, I have scoliosis upper and lower curves maybe in the 30 s or so; also have DDD, a few herniated disks, stenosis, multiple schmorls nodes, retrolithesis, etc. have chronic pain -started as low back pain, seems to be moving up (over a number of yrs) to the thoracic spine, neck. But in the last month I noticed an odd oval shaped depression just above my left shoulder blade ( I have been having severe pain at times in the left shoulder joint itself and moderate to severe pain all around the shoulder blade). What could be causing this odd oval depression?
