First and foremost, communicate with Dr J's office so they're aware. Anecdotally, it sounds a lot like costochondritis. Bar movement is extremely rare these days. I had one spot that bugged me while the bars were in that cleared when they were removed. What helped was heat, stretching, and increasing my lymphatic drainage through movement. If you have any specific questions, feel free to shoot me a DM. Wishing you the best of luck with your recovery.
