I have posted I’m a few groups hoping for some guidance. I have had left rib pain and really arm and shoulder pain for a few months. I have had many heart tests and spent a many days in Er due to my anxiety.

Main issues I have are almost daily I have left rib cage pain. Usually under my pectoral. I also have lightheadeness when this happens that last for s few hours.

It’s puzzling as well as frustrating because GP can’t give me any answers either. He says costochondritis but I’m not really buying it withnother symptoms. I sit in a Desk all day and am inactive so was wondering if my spine and posture may affect this. Or is it condritis? Need guidance from maybe people with experience
