So about a week ago I started to get short stabbing localized upper rib chest pain. The pain is intermittent it hits and goes and comes back randomly throughout the day. Itís not a bad pain maybe a 3 on a 1 to 10 scale but it gets my anxiety going through the roof everytime it happens. Naturally Iím worried it could be my heart but seeing itís a pinpoint pain and not squeezing or crushing hopefully itís not. Which makes me wonder what it could be? Please does anybody have any insight on what it could be pulled muscle gas? Can those even last that long? Thanks
