What Causes Pain In The Right Shoulder And Numbness In The Fingers?

HI, I have a pain area on the top of my rt shoulder on the font of my shoulder as well as numbness sensation down my arm into my fingers, weakness especially the tricep muscle, tender on back of shoulder blade as well as neck, pain worsens when looking down, numbness/pins and needles get severe if resting elbow on a table ie: while typing, had mri + xrays on shouder and neck and both showed nothing other then small partial tear of the supraspinatus (low grade).. only suggestion now is extensive physio to strengthen the muscles? I m still not certain there isn t something being missed... Injury was 9 months ago with 2 months of physio at that time there has been no improvement since then symptoms are only getting more severe.. shoulder impingment and c6 pinched nerve was the thoughts by specialists but nothing has shown up on tests...
