Is there a way I can isolate the shoulder to prove its the shoudler, and not the elbow/forearm/wrist causing the issue?
Yes, it is all related as the body is a system of systems.
Tight forearm can cause compensations your may or may not be aware are happening at the elbow which changes positioning and feeds to compensations at the shoulder.
