Shoulder crepitus that causes discomfort and weakness
I'm 26 years old, have mild lumbar thoracic levoscoliosis (15 degrees). I'm right handed and used to work on the computer a lot (but not anymore, resigned from my work 2 months ago)
I have tight knots on my right shoulder, it also feels weaker compared to my left. What really bothers me though is the continuous crunching and popping sound my right shoulder makes whenever I move it upward or downward. I've done 8 physical therapy sessions but it doesn't seem to help. My xray doesn't show anything.The crepitus is not painful but my feeling on my shoulder is very uncomfortable.Unless the mousearm is supported at the elbow, the shoulder takes a lot of strain; it should be happier now you're spending less time on the computer.
It's generally considered there are four joints in the shoulder:
Which of these is popping and crunching? Can you tell?
Is that weakness in the shoulder associated with pain? That simply means you can't give a full contraction because it hurts.
True weakness, in the absence of pain, needs to be evaluated. Do you know if there are any reflex or sensory changes?
