I tweaked my bad shoulder enough that I thought I had really done myself an injury. My OD told me today that it was Pec Minor Syndrome. In our discussion we covered my first rib and scalenes. It is great to have a doctor who doesn’t immediately turn to surgical consults or drugs!
You are a system of systems so yes it could be a cause.
Trigger point may be something to add to what you are doing.
Jeff Alexander has a great site with alot of information available http://smr.networkfitness.com/smr-categories/
