Dear Simon, thank you for your question. The symptoms you describe could be
recurrentRecurrent cystitis angina but are atypical because the chest tightness lasts for several days after exercise. I doubt you are injuring your chest muscles with exercise to cause this problem. I have no other ideas as to what could be causing your chest tightness, but you should alert your cardiologist who may want to perform a stress test. Additionally, you should ask your cardiologist about treatment with a beta blocker which we know improves long-term survival after a heart attack. I hope you find this information useful.
