The last one gave me the biggest scare, because I checked all the other things (done oh so many EKGs (maybe 10
XD), went to a cardio doctor who assured me (after a one hour long heart ultrasound with Color Doppler) that everything was ok with my heart, and I checked my lungs, spine, blood and what not. So of course, I thought it must be the aneurysm. Its my "last option" and I was really scared of it.
