Bad breath caused by chunks from throat

Hi, What can I do for my bad breath that is caused from white little chunks that come from a sack along the side of my throat. This is what my doctor told me. I know its true because I can swallow up and pieces come up and sometimes my throat hurts when the sack gets to full. The pieces break off and come up. They smell bad, like crap. Ive tried everything from mouth wash to digestive coverups. The only thing I can do is chew gum all day or suck on mints and it sucks. Because I dont want to use that stuff becuase of all the chemicals. Please help Tweet
