HI, i am 14 and ever since i have known every time i lift my arm up my shoulder (where it joins to my cola-bone ) clicks and when i put it down it clicks, i can feel it and it makes a noise just like when you crack your knuckles. It happens every time, and more so if i have a shower or do sport or when i move it alot. Sometimes it hurts at the end of the day, but i was wondering is it anything to be worried about or does anyone no why it does it ? Please it is staring to get annoying ? thanks :)
