Hi LeeBee,
I get them at the moment when walking fast - usually I am trying to get somewhere/back to work after lunch -maybe that means I'm more anxious? Cos higher heart rate I reckon we feel them more, more uncomfortable and stronger aren't they?
I just can't stop that nagging worry each time I get them, even though fairly sure don't have a heart problem.. I hope - why is it so hard to reassure yourself? I could drag myself to docs everyday with worry...
