Just saw your comment after searching google and made an account on here because I have a lot of the same issues. I felt relieved when I saw your post because I was starting to think I was crazy. I have Pain in the same spot in between my shoulder blades. And sometimes under my shoulder blade. X-ray was normal. OTC pain meds occasionally work. Muscle relaxers don’t work except make me tired and help me sleep and my pain typically happens at night. I’m having a hard time getting my doctor to set me up with an MRI or CT. Went to the emergency room last night because I had horrible intense pain in my back and in the middle of my upper abdomen and was worried it was a gallbladder issue. As sometimes that can cause pain in your upper back as well. They were no help. Gave me yet again another x-ray that came back normal. I’m having trouble getting taken seriously. Maybe because I’m fairly youngish (35) I have an active job as a Certified nurses assistant and I’m assuming I got injured at work at some point. Physical therapy hasn’t helped either. I’m going to try acupuncture soon. It’s starting to greatly affect my quality of life.
