as i said - i am not a doctor... You really cannot diagnosed that type of thing without further studies - it sounds to me like a problem with your "swallowing mechanism"

You need to get some diagnostic testing. Have you had a barium swallow? this shows how your esophagus is working and if you have "reflux" where the food refluxes back up. You swallow this liquid, barium, and they take x-rays while you are doing it.
