I wanted to find out what to do...i had recently gone to eat, i was eating peacefully until i felt that something went wrong when swallowing ?

Ok what do you mean: Sudden pain? Things down the wrong pipe? That's an important distinction. If you felt a sudden sharp pain that then went away and has come back, you need to be checked for a possible foreign body that could have perforated your esophagus. This is more likely if you were eating something that had been cooked on a grill (wires from the cleaning brushes can get stuck to food) or if it had small bones
