What Causes Pain Above Ribs After Vomiting And Pain While Swallowing?

I drank two beers and maybe a bad clam last night. Got up out of bed to throw up but was holding it back cause I was in the kitchen. I didn t make it outside so I threw up in the sink. Not a violent one just a couple heaves and it s over. I suddenly have this pain below my chest bone in between the top of the ribs. I hurts to swallow and it hurts to much to burp. I think It s the organ or muscle that contracts to allow you to burp. Is this serious or do I just walk it off.
