What (if any) specialist to see?
So I have a slight shoulder issue on my right side. A little background, in 2010 I had a mountain bike crash where I compressed 4 vertebrae just under my neck. That took some time to heal but I now have no back pain whatsoever from it. What I have had since then is tendency to develop tightness just to the right of my spine next to shoulder blade. Also in that spot there is a very consistent and pretty loud "Pop" ever time I rotate my right arm in reverse circles. It occasionally pops while rotating in forward circles but always in reverse. There is no pain associated with the pop and there has never been. I have seen PTs and a Chiropractor about this but that has never really gotten me anywhere. Its has never been a problem in daily life and as long as I keep good posture I have no pain and the extra tightness I get is easily resolved so I had just decided these are effects from the back break I need to live with.
