Has anyone experienced pain in the back and shoulders?

I’ve had pain everyday in my back and shoulders mostly on the right for 4 months. MRI’s were completed and it was determined that I needed a right shoulder replacement. The continued pain that has radiated concerned me so I had RA bloodwork done.
My RA factor came back as a whopping 267.2 but my ANA is negative. CCP is less than .5 and SED rate is 34. Needless to say, I cancelled my surgery to address this. Anyone else have anything similar?
