I Had A Frightening Experience Today....had Just Finished Eating A

I had a frightening experience today....had just finished eating a lunch dish with a lot of rice. Afterward I felt like it was lodged in my chest. My chest felt full, tight, and I thought I was going to pass out. I suddenly got very sick and began to vomit. That eased the pain. I've had a feeling of "food not going down" before when I've eaten certain bread products but nothing like this!
