After suffering extreme pain for 3 years 24/7 in my right shoulder and ubable to lift my arm shoulder high or get my arm behind my back I finally had a complete shoulder implant and the pain was gone when I woke up after the operation and 6 months later I have complete use of my right arm no pain and I can again smile something I was unable to do 6 months ago.I strongly suggest you contact an orthopedic surgeon for a complete examination (Just a suggestion)
