I Had Shoulder Surgery 1 Month Ago. He Shaved Off

I had shoulder surgery 1 month ago. He shaved off some of my collarbone and repaired a small rotator cuff tear. I have some popping when I move. More now that I'm not wearing the immobilizer. My dr knows. He thinks it's scar tissue. In to start physical therapy in 2 days. I'm having a lot of pain and the popping. Does this sound normal?

Never mind. Didn't know there was a charge.
