Just had a horribly sharp pain the chest

Freaking out a little bit over here. I just had what felt like a sharp jolt on the right side of my chest. I could feel it in the front and the back......like it came from my shoulder or something. Kind of took my breath away for a couple of seconds. I feel like I can't breathe right now but I know that's just my anxiety and panic. Has this ever happened to anyone? My HR is fine on my Fitbit.

I’ve had this happen before. Through the heart. Sometimes Through my lung but it stops and nothing else comes of it. I freak out about it but forget it after a couple hours and nothing else bad has happened…

I get this from time to time, it feels like a charlie horse or sharp muscle spasm for me. Very quick, lasts like 2 sec but very sharp. Nothing ever comes of it for me either. I assume it’s just muscle spasms bc of chest tightness that I get sometimes w my anxiety.
