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.
Thanks for this revelation. It has a name! All my siblings got these and they told me “it’s a gas in your lung” which i ran with for years, haha. Once, still as a kid, i got it for 6 hours so we called a doctor. She diagnosed it as intercostal neuritis triggered by high and unusual physical excertion the previous day. Prescribed nothing
