Last night was the first time I noticed this. My middle back (like where your bra fits around) I had this moderate back pain on each side of my spine then it ended up coming around to my ribs making it hard to breathe kind of like someone was sitting on my chest. I have neck issues C5-6 ACDF almost yr ago with almost no fusion and got informed month ago I have C6-7 and L5-S1 ruptures too. Can it be from either one of these area or is there a chance it is the T levels? Doctor told me I have DDD and Spinal Sten. and some arthritis issues (looking further into) Just want to see if anyone else out there has had this issue and what was told made this happen. Thanks.
