Hi. I ate a tortilla chip a couple hours ago, and it feels like there's a piece of it caught in my esophagus (roughly in a straight line from the point on the front of my neck between my collar bones back through my neck to the esophagus, almost in my upper back). I would have thought that it would have dissolved and gone down to my stomach by now, but I still feel a lump there. I've tried drinking warm water and eating a piece of bread, but no luck. Is it possible that it's a scratch or irritation in my esophagus from eating the chip?
