Maybe?
I felt the same thing when I was much younger than you back
then.... VERY SHARP PAIN... What I didn't realise later was that
I've developed some cardiac complications (I've got family history
but was practically 'normal' before I made discoveries during my
NS...)... I'm not sure if they're related issues, but perhaps
certain level of stress or pain might have worsen my potential
disease?
Anyway.. Just thought perhaps you might like to see a specialist?
But then of course... It really depends on how 'physical' yuor pain
really was...
