I relate to the back and chest thing, in that the pressure and soreness foe me is (also) on both sides, essentially opposite of each other. In the process of interviewing new PCP as mine has retired. My gauge is how much attention they pay to these symptoms as my primary concern. The 1st interview the dc simply ignored them and focused on the process to enroll me as a new patient. I realize that concern and being able to help are not the same thing; but figure I need to select someone who at least acknowledges what my primary concern is.
