Pain on the left side of my upper chest when I yawn? ?
I noticed when I yawn or if I press my tongue down (as if I were yawning) I get this strange pain in my upper left side of my chest. I’ve been noticing too that I hiccup every time right after eating. I just had an endoscopy done for stomach pain (which has gone away with omeprazole) and they didn’t find anything. What could this chest pain be? Acid? I’m not feeling any reflux
