question: Im having a sharp pain on the left side of my chest when I move from my left to my right. It is very brief. I had an EKG yesterday and everything came back fine. Im a 30 year old male with no previous condition. Im going for a stress test friday but this scares me. I know im panicking and need rest. This pain is really brief again. As im sitting here i feel fine. Im hoping for a piece of mind if anything so I can go back to sleep. Should my stress test be sooner than this friday. Im wondering since its real brief if this isnt just a pulled muscle. Im taking gerd medication right now which is what my pcp thinks this is. Its just this short brief pain on my left side is scary.
