PT trouble
I was diagnosed with frozen shoulder in addition to whiplash. I went to physical therapy and they gave me traction, heat, massage and one day decided to "break loose" the frozen shoulder. It hurt like Hell and made the problems worse. I had Anterior Cervical Fusion and Disectomy on foul levels in my neck and the shoulder pain was still there. MRI's showed extensive massive full thickness tears of the supraspinatus, infraspinatus and bicept tendons. I have had four surgeries on my shoulders, and the only time I can remember injuring either shoulder was when the Physical Therapist pulled so hard to break things loose.
