Had a spell when I was eating a piece of meat, swallowed some then got the hiccups, and can't swallow then,have done this before, usually goes away, or go to the bathroom and kind of throw up some mucus like stuff with some food in it, then goes away and am okay To night it was quite awhile before I got rid of it, but the hiccups keep coming back. Pretty good now , but wondering what it could be.
