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.
I even went to the doctor once because I had it a few times a week some years ago.
Me, too. Used to have it quite often. GP said it comes from bad posture. So I changed that, and also started working out more. It went away for good.
I think for me it had to do with bad mental health
