Do you think an mri with contrast of the shoulder ( arthrogram ) might be appropriate to see if things have changed. A shoulder specialist is recommended for a consult if the shoulder continues to hurt. What is Dr. Sanders opinion of your situation. No doubt you are tired of this, but you have gone this far don't give up now, I know it is easy to give others advice when the person being advised has to do the hard part.

I hope things improve
