Can you tell me in my throat. It extends all the way from my chest to the top of my esophagus, and I know there is my last meal sitting there. How?

Diverticulum? Your question is vague,if you burp up old food,have bad breath,or regurgitate food ,for example breakfast later in the day,in some people ,a divertculum or a pouch may have developed,through a weak muscle,some people with a large hiatal hernia,gives a bloated feeling,a GI consult may be appropriate .
