Question: I have, for the past three years, suffered with reoccurring tightness, pain, swelling feeling on the left side of my chest. It started out three years ago as a sharp pain, like a knife in my heart and then radiated to my jaw, down my left arm and behind my shoulder blade. Well, when this would happen, I thought I was having a heart attack and my blood pressure would go off the charts. I went to an insta-care during one of these attacks and was sent to the hospital. I was checked out and told my heart was fine. I was later put through all kinds of heart tests. It was determined I had chest wall inflammation. Once I knew it was not my heart The symptoms calmed down. It was like it was also stress related. A year later it started up again. I changed doctors and the new doctor insisted I go through the heart test again. Nothing was found. December of last year I was diagnosed with breast cancer in my left breast with pre-cancer in my right. I under went a double mastectomy. Well, I am now dealing with the chest problems again. It is not as painful now, but the tight feeling with uncomfortable heat on my chest radiating from my chest to my jaw. I am now worried about my heart. You know a little anxiety. Do you think it is my heart or costochrondites?
