Hello Doctor,11 months before I try to lift an heavy Weight bag, suddenly a slight pain and a pop up sound occurs on my shoulder,but after 3 days pain is gone,but still when I rotate my hand vertical towards body on standing position,there is a pop up sound on tricep area and elbow joints,but there is no restrictions and pain in movements,all this happens on my left side arms,but on my right side arms,same pop up sound occurs but only one time,on my left side sound occurs at every rotation,it's normal or not?
