I am a runner who noticed a dull pain in my heart area that would not go away. I only noticed it when I took a long breath or try to lay on the left side of my body. After 5 days I tried to run an noticed it getting worse. I knew something was going on and went to the local hospital. They told me I had to go to ER for this. To make a long story short, I had several EKGs, Angiogram, and stayed overnight in the hospital. Initially the doctor said the EKG showed a mild heart attack but actually wasn't.There is a term for this but forgot what it is called. As it turned out, I was told the constant dull pain was NOT cardiac related. My lungs were clear. I did find out I had 50% blockage in a side artery and am taking blood thinners for this.
The dull pain has subsided somewhat - I can run but I still feel there is something there when I take a deep breath and lay on my one side. Is this in my mind or what? I am 52 years old.
