I Was Eating Dinner And The Food Stopped What Feels

I was eating dinner and the food stopped what feels like right above my stomach right above my diaphragm. Then hiccups, then throwing up what I had just tried to swallow. For the last 5 hours the knot has not gone down and if I try to ingest even water I will throw it back up. Also when I start to burp, massive amount of bubbles come out. As it stands right now, I cannot get water down without it coming back up.
