I have an occasional choking problem when eating foods. It usually happens with rice but it has also happened with other foods. I feel like esophagus is slowly pushing the food back up and I cant breath well until I throw up the food. Then I can finish my meal just fine. At first I was thinking that maybe I was eating too fast but it happened last night with white rice and vegetables and then today again when I was making sure that I was chewing very thoroughly and slow. It is not a burning or acid feeling at all.
