I'm 6 or 7 weeks out and I am getting over a chest cold. I had a really bad coughing spell in the middle of the night last night. I thought I was going to cough up a lung. Ever since that coughing episode, I have had more chest pain in my sternum and over my heart since then and also hurts more when I do cough now. Seems a little scary to me like did I cough the stitches in my valve loose? Then common sense took over and realized I couldn't do that 6 weeks post op. So I really don't know why I am experiencing more pain since that coughing spell.
