On Tuesday Morning I Woke Up Feeling Like A Marble

On Tuesday morning I woke up feeling like a marble was stuck in my throat. I can't swallow anything without it causing sharp pains equally in my chest and back. On Wednesday I went to the e.r. because I woke up screaming in pain. They did exrays, e.k.g., and blood labs. Everything came back normal and now I can't eat without having to through up because my food doesn't feel like its going down. Yet I am only throwing up white bile, opposite color of the food I ate. While at the hospital they gave me morphine and xophran and it help me sleep but little for the pain. I am not running a fever and have no signs of being sick. Please help me in any way you can, thank you staci dake.
