Costochondritis or diaphragm muscle pull
I’ve had a pain for six months on my left side underneath my ribs close to the sternum. It feels like something is “in the way.” Have had every test possible for stomach/intestines – nothing abnormal. One doctor says it’s costochondritis, another says a diaphragm pull, PT says elevated rib. Pain is mostly when I do abs, intense cardio, or lie on the leg extension machine. Rest doesn’t help – any suggestions………………
