I get that when I haven’t eaten, maybe it has to do with that?

Oo I get this too and it’s never been serious for me and usually goes away after a while I’ve noticed I get it when I have trapped gas lol but it’s always totally scary!! Could also be from sitting or working for long periods of time in a crouched or different position? If you have other symptoms with it then I would see a doctor just to be sure!

I get that when I'm hungry sometime, otherwise for me it's either gas or a cramp in between my ribs in the little interstitial muscles. Shouldn't be serious, of course this is just anecdotal

How about after being to Charopratic?

It happens really commonly for pretty much everyone. Stretch to the opposite side and take a breath. Make sure you're stretching your ribcage. It helps most of the time
