angina or something else

[LuvToHike]

I'm trying to figure out whether the chest pains I get are angina or from something else.  I get chest tightness when I get stressed.  Feels like someone is pushing as hard as they can against my sternum.  It lasts a few minutes, goes away and may come back several times in an hour, or not at all.  I'm 50 years old, not overweight, don't smoke, good cholesterol, BP is generally good (except when I get stressed, it can spike up to 180/90), heart rate is similarly good (except when stressed, where it will race).  These chest pains can occur daily/weekly for months, disappear and reappear several years later when stress reaches unacceptable limits.  I don't have Acid reflux, so what do I have here? Any ideas?

I've tried vitamin B as well as other vitamins, they make me nauseous.  When I remember, I can take the chewable Centrums.

Cholesterol LDL should be 100 or lower.  HDL should be in the 50's or higher.  Blood pressure should be 120/72 to be perfect.  Spiking to 180/90 under stress is high.  Have you tried a good vitamin B stress tab to help with stress?
