Pop in the center of my chest

[dinnerroll]

so like 15 minutes ago i was sitting in my computer chair and felt this pop feeling in the center of my chest. it didnt really feel like it was on the sternum, more like beneath it. i feel dumb asking but what could this be? the first that that jumped to mind was PE.

i sometimes get that feeling. i usually just ignore it. One day I decided to freak out about it and I felt it for like a week until I finally calmed myself down to believe it was nothing and now it doesn't bother me when it happens. Can't tell you what it is but it hasn't killed me yet so I think its fine!!!!

Probably muscular or GI related.
