I am aware of the different comorbidities potentials for causing chest pains. what initiated my inquiry was that I have had resent chest pains. These pains (three different times) were very very small finger tip type pains and each time I took a 1/2 nitro and the part that has me questioning things is, after the nitro the pain did stop (which I know would indicate angina), however I have so many other things that could be causing (My Emphysema, my back pain issues from hell, aortic aneurysm, my heart failure) chest pain it is confusing.
The only history I can relate is prior to my 1979 triple bypass I did have "one time" finger tip very light type chest pain (hard to call these pain, because they did not hurt)
which I guess could/would be labeled angina.
