Why histamine surge cause heart pain in swimming? I get armpit rashes if exercising 1min. I get moderate pain in heart in 45min so have to stop.

In brief: Not from histamine

Despite your age, you need to get your cardiac status evaluated before you exert heavily again.
This may be a warning sign of something serious and potentially life-threatening.
