Hello, thank you. Well, I was previously diagnosed with Costochondritas (sp?) very painful ribs on my left side, a deep radiating pain. It would go away after a couple months but come back every once in a while. Next Dr. said it wasn t costochondritas but just pulled muscles. Well, it keeps coming back now every few months and now it is the middle of my chest bone. It feels like it was cracked wide open when ever I take a deep breath. It is also still radiating on the left rib cage. I got to the point where I was taking so much over the counter pain med s I developed a small ulcer. Help!
