Hi. (Prior to this I was diagnosed with Pericarditis) I ve been seen by 3 doctors and was told that I have Costochondritis. I have been given anti-inflammatory, ibuprofen, Nexium over a 4 month period but nothing helps. Just recently over the past week I have been in more pain than ever before, hard to breath PERIOD. I m in constant pain all day whether I am laying down, walking, brushing my teeth, scratching my head anything non-movement/movement I am in pain (pressure, tightness, my heart feels like its working harder. The left side of my sternum is swollen, left breast is swollen. The swelling is visible. My left side arm, shoulder, back joints hurts. One of my Dr s have done quite a few EKG, chest x-ray, stress test, blood work. I have a healthy heart. I am in great shape, eat healthy, WAS able to work out 5-6 days a week maybe 7. I have been dealing with this for quite some time and im not sure what else to do but continue to pray. I have read about the cortisone injections and have an appointment Wednesday. Is there anyone who can give me some advice on what I can do next? I ve been on short tern disability and off work going on 4 months now.
