I had a PM inserion (left side) just a little over a year ago for complete heart block. After 6 weeks of limited range of motion (ROM) for the arm (per drs. orders), I develped frozen shoulder syndrome. I went to a massage therapist and she helped me with the majority of the pain and ROM. I still have pain in my arm and now I believe that this is due to the PM hitting up against nerve/nerves. The PM is underneath the skin. Has anyone else experienced this? I have consulted my Cardiologist that inserted the PM and he indicated that the PM should be moved to go under the mucle.
