A good chiro should order x rays at the very least.. especially after hearing all symptoms and concerns... but they should be able to do a fairly good evaluation. But after the x rays are done would be best.

My chiro adjusted my wrists, elbows, ankle, shoulder... just about any joint- a good one can do it perfectly.

The top ribs are very close to the collarbone/clavicle, that is why poor posture (forward head /forward shoulders) or accidents can make the two of them pinch on the nerves or the blood flowing thru the area.
Plus the scalenes are attached too and they cause trouble when they get tight or spasm.
