I was eating some hard, crunchy tortilla chips with some hummus on the side. I swallowed a chip and instantly felt a very sharp pain in my throat as it was traveling down my esophagus but I am not completely sure if it went into my stomach. It has been 2-3 hours since that incident and now it feels like I have something in the back of my throat, small heartburns, and coughing as well. But I am breathing, eating, and drinking normally with no problems but I still feel something is in the back of my throat.
