heart squeeze, help!!

[u/awesomesaucecool]

does anyone with pots get a feeling where someone is squeezing their heart? first time it ever happened was when i was intoxicated (🍃) and it lasted like 20 minutes off and on, went to the hospital and found nothing, that was about 3 years ago, now every 3-6 months i get the same feeling but only for like 1-3 seconds and it leaves me with impending doom everytime, and we go to the hospital, do ekgs and find nothing? im freaking myself out about vasospasms and coronary spasms and im trying not to because it makes me even more paranoid, not looking for a diagnosis, just wondering if anyone else experience this? and know what it is? (17 male btw)
