I'm just chimming in Kimber only because I've had upper back pain since I carried my first baby. Yeaaaaaaaaaaarrrsss later, I have chronic upper back pain, but it's caused from a hole in my spine which is beside the point. The point being that I know how bad upper back pain can be. I am certainly not a doctor, I reserved that to several other members of my family of origin. But I agree that your upper back is very, very probably due to "giving" to your surgery area. It is amazing how our bodies work, but not so fun sometimes. I really hope that you get to feeling better very, very soon! You're in my thoughts.
I'm called Cat, but as there are few other Cat's on here, I put the number of cats I have and combined it to spell out Catz4
