Just want to ask, I have a problem with my shoulder "popping" (my doctor says its not really popping as in dislocating just a slight movement). during service motions. This makes my arm really sore for a couple of days each time this happens. My doctor says its due to my deltoids being too strong relative to my rotator cuff so apparently my scapula or shoulder or something isnt moving in tandem. Would the best way back be just to work on my rotator cuff muscles? I gave physiotherapy a miss cause my arm healed pretty quickly each time it happened so I assumed there wasn't any problem with it. Also due to those shoulder injuries I have impingement in my shoulder (internal rotation) like one of the earlier posters mentioned( can't scratch the back of the other shoulder without pain). What would be the best way to increase my mobility? Thanks in advance for any help.
