The good news is that (other than the pain) it is completely harmless.
The way it always felt to me is like someone wrapped a small wire around something tender in my chest, and if I tried to breathe or straighten my posture, they would yank on it. I’d get it anywhere from a couple times a week to once a month. Then one day in my mid-30s it just stopped.
From what I understand this is relatively common. I was so grateful for the person on reddit who dropped this nugget of wisdom several years ago. It was nice to know I wasn’t dying or whatever.
Holy shiit that has a name?! Every once in a blue moon, I’ll be just sitting minding my own business then BAM! Ass lightning like Thor stabbed me in the ass with a blade that has lightning wrapped around it. Then just as suddenly as it came, it’s gone…
I’ve called it ass lightning for the past few years. At least I know I’m not alone!
