What causes shoulder pain to be worse at night?
I'm not sure, how can I tell which one it might be?
A doctor or physical therapist would be best able to diagnose the cause of your shoulder pain. However, there are some symptoms that may help you narrow down the possibilities. For example, if your pain is more intense when you lift your arm or at certain angles, it could be tendinitis or a rotator cuff injury. If you have stiffness and can't move your arm, it could be frozen shoulder. Does any of that sound like your symptoms?
