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.



Description is pretty spot on, but it’s on the opposite side for me. Are my innards flipped?
It’s possible. Very small chance but it does happen.
Would that make it more likely for me to be left handed? Because I’m very much right handed.
