[|Human|] I have skin numbenss without tinglingon my left side in my underarm,underside of upper arm and half way across my left side of chest. At times my upper back on left side is numb also. MRI showed a bone spur c6 c7 without empingment. MRI did not include thoracic. Have had severe pain w stabbing and burning in upper back for 6 days. Can you advise me as to what could cause this .
[|AI|]  In my opinion left thoracic pain can be radiating from C8 nerve root (C7/ T1) also upper back pain from C3/4does not have to show on scan but can be mechanical or from muscle tension I recommend physical therapy focusing on treating you round shoulder by stretching your pectoralis muscles and strengthen upper back muscles also when sitting on a disk you should pull your chair forwards till your belly touch the disk Good Luck
