I feel it as an intense cramping BURN miid-chest as if I swallowed strong acid. When it is at its worse the "burn" radiates to both shoulders and up my neck.
For me there is often an element of stress involved with exercise.
My exercise alone tolerace is quite high but add to it the fear of missing a train and I can bring on angina.
It is neither crippling nor slight but mid-way. It is always accompanied by a sense of fear (naturally
.) A frequent scenario is a run for a subway and once inside and standing still THEN the pain comes on.
Before my angioplasty, a CERTAINTY to bring it on was walking into an icy wind in the morning.
Stable angina, the most common kind, will go away after 2 minutes or so.
Do as beefsteak recommends to check your angina level by RUNNING for 5 minutes or more. It think if you can run at 6-10 mph. for 5 to 10 minutes, you can probably forget about angina for the next decade.
